Lavoisier discussion about the Bottom-up Synthesis of Graphene Related Materials

On January 22nd and 23rd, a Lavoisier discussion will be held on Bottom-up Synthesis of Graphene Related Materials on the plateau de Saclay (south-west of Paris area), France.

For all details, please visit our website.

The bottom-up synthesis of graphene related materials such as graphene quantum dots, nanoribbons and nanomeshes (GQD, GNR and GNM) is an extremely prolific field of research. Materials with highly controlled structures and properties have been developed by “on-surface” synthesis or by synthesis in solution. This workshop aims at federating the French and European communities working in this field through tutorials and presentations of the most recent results. It is dedicated not only to confirmed researchers in the field but also to young researchers who want to initiate projects on this topic and take part of this activity.

The workshop is organized by IRAMIS (CEA Paris-Saclay) and LuMIn (ENS Paris-Saclay) and will take place in the new building of the ENS Paris-Saclay.

Lavoisier discussions series are prospective workshops on research areas covered by the national research group (GDR) and the international coordination network (IRN) related to low-dimensional van der Waals heterostructures HOWDI..

The two groupements de recherche (GDRs), NS-CPU (Nanosciences with near-field microscopies under ultra high vacuum) and HOWDI (Heterostructures of van der Waals materials with low dimensionality) jointly organise a two-half-days workshop. The objects of interest, 2D materials and their heterostructures, are essentially surfaces. They are hence ideally suited to investigations with high-resolution local probes.

Topics covered by the workshop :

Photonics, including single-photon sources, exciton localisation, role of electrostatic disorder
Magnetism, including isolated or in-interaction spins, magnons and moiré effects
Electronic correlations, including spin impurities in 2D semiconductors, superconductivity, charge density waves

Location : Université de Paris Cité, Paris (13eme) 6-7 Feb, 2024

Hexagonal Boron Nitride : New Theory Developments on a Well-Known 2D Material

Ludger Wirtz

Department of Physics and Materials Science
University of Luxembourg

Layered hexagonal Boron Nitride (hBN) is often used as a flat, clean, and well-insulating substrate for the investigation of graphene or other 2D materials. But its intrinsic optical properties - in the deep UV - are interesting by itself : the strong luminescence and its potential for UV-lasing was discovered in 2004 [1] by the group who still distributes high-quality samples of hBN to the whole 2D community. The presence of huge excitonic effects in bulk hBN was theoretically established by ab-initio calculations [2]. Soon afterwards, it was established that the binding energy in single-layer hBN is even 3 times higher [3]. Since then, the surprising complexity of the luminescence spectra of this seemingly simple material (with only 4 atoms per unit-cell for bulk hBN and 2 atoms for monolayer hBN) has attracted a lot of attention by theoretical and experimental groups likewise. A lot of the recent progress on this material has been achieved by (or in collaboration with) French research groups.

I will discuss the role of crystal symmetry in the optical spectra of hBN and explain how to understand the luminescence of different phases of BN from a theoretical/computational perspective, taking into account the strong excitonic effects and its coupling with phonons. I will give a perspective on non-adiabatic effects in the Raman spectra of bulk hBN and on the understanding of the substrate-dependence of the luminescence spectra of mono-layer hBN.

Epitaxial Growth of 2D Materials and Heterostructures

Abstract :

Van der Waals (vdW) heterostructures combining different 2D materials
have a great prospect for the realization of atomically thin devices
with tailored properties. To achieve a high density, bottom-up
integration, the synthesis of such heterostructures
via vdW epitaxy is a promising alternative to layer transfer, which is
problematic in terms of scaling and reproducibility. Nevertheless, due
to the weak bonding between 2D crystals, vdW epitaxy is sensitive to
various surface defects, usually leading to uncontrolled nucleation and
thus non-uniform growth of polycrystalline material. In this talk, I
will present results on molecular beam epitaxy (MBE) of hexagonal boron
nitride (h-BN) on graphene/SiC(0001). Specifically, I will discuss how
defect engineering in graphene can be employed to exert the control over
nucleation and thus to realize selective area growth of h-BN. In
addition, I will show our recent studies on ferromagnetic vdW
heterostructures with perpendicular magnetic anisotropy and high
transition temperatures, which were realized via MBE growth of the novel
2D ferromagnetic metal Fe5-xGeTe2 (FGT, with 0 ≤ x ≤ 2) on graphene as
well as h-BN templates.

Les 23 et 24 janvier 2023, une discussion Lavoisier sur les matériaux magnétiques 2D aura lieu à Strasbourg.

La récente démonstration d’un ordre magnétique intrinsèque dans les matériaux de van der Waals atomiquement minces ouvre un vaste champ de recherches pour comprendre et contrôler le magnétisme à l’échelle nanométrique. Cette classe naissante de matériaux offre une grande variété d’ordres magnétiques, de la phénoménologie usuelle à des états de spin plus exotiques. Des matériaux magnétiques 2D peuvent être intégrés dans des hétérostructures de van der Waals, où de nouveaux phénomènes spintroniques et nano-photoniques émergent, favorisant des percées dans les sciences fondamentales ainsi que l’ingénierie de futurs dispositifs ultra-minces.
Cet atelier vise à fédérer la communauté française travaillant sur ce domaine de recherche en plein essor, sur un format court propice aux échanges. Le programme comprendra trois conférences didactiques sur des sujets spécifiques donnés par des experts ainsi que des présentations orales et par affiches des résultats récents.

Les discussions Lavoisier sont des ateliers prospectifs sur un domaine de recherche émergent proposées par le groupe national de recherche (GDR) et le réseau international (IRN) lié aux hétérostructures de van der Waals de basse dimension HOWDI. L’événement est organisé par l’IPCMS, un institut de recherche du CNRS et de l’Université de Strasbourg.

Abstract :
Probing magnetism in atomically thin van der Waals crystals is challenging because most experimental methods commonly employed to study bulk compounds are not sufficiently sensitive to detect any magnetic signal from such a small amount of material. Here, we will discuss how magnetotransport experiments can circumvent this issue in rather simple Ising type ferromagnetic and antiferromagnetic insulators. Moreover, the complementarity of magnetotransport and magneto-optical probes allows determining the phase diagram of more complex magnetic structures of atomically thin crystals. We will conclude the talk by discussing interesting newly discovered atomically thin materials in which we probe the coupling between magnetic and electronic properties.

Quantum spins and hybridization in artificially-constructed chains of magnetic adatoms on superconducting 2H-NbSe 2

Prochain séminaire virtuel du GDR HOWDI : Mardi 8 Février 2022 à 11h.
Katharina FRANKE (Freie Universitaet, Berlin)
"Quantum spins and hybridization in artificially-constructed chains of magnetic adatoms on superconducting 2H-NbSe_2”

Résumé :

Magnetic adatom chains on superconducting substrates are promising platforms for topological superconductivity and Majorana zero modes. Signatures of these have been found in densely packed chains with direct exchange interaction among the adatoms. In contrast, the dilute limit of chains, where the atoms are sufficiently far spaced that direct hybridization of their d orbitals is negligible, but close enough for substrate-mediated interactions, has not been investigated previously. Engineering dilute adatom chains with substantial substrate-mediated interactions requires samples sustaining long-range Yu-Shiba-Rusinov (YSR) states. While these decay
quickly with 1/ 𝑘 𝑟 (with 𝑘 being the Fermi wave vector and 𝑟 the distance to the impurity) on three-dimensional superconductors, the decay of YSR states on two-dimensional superconductors is much slower, scaling with 1/√ 𝑘 𝑟 [1].
Here, we explore the well known quasi-two-dimensional superconductor 2H-NbSe 2 as a substrate for magnetic adatom structures. Individual Fe atoms induce Yu-Shiba-Rusinov states, which spatially extend over several nanometers with their energy and symmetry influenced by the crystal field and by the co-existing charge-density wave (CDW) [2]. When two Fe atoms are placed on equivalent adsorption sites at a distance of 1 nm, the YSR states are shifted in energy and split. While the splitting indicates hybridization of the YSR states, the strong shift can only be explained by RKKY coupling of quantum spins [3]. We deliberately increase the chain length by adding individual Fe atoms with the STM tip, up to a length of 51 atoms. In each step we track the evolution of the YSR states. We find signatures of YSR band formation consistent with ferromagnetic coupling of quantum spins [4].

Proximity effects in van der Waals heterostructures
Friday, 3 dec 2021, 14h

Le prochain séminaire virtuel du GDR HOWDI aura lieu le vendredi 3 décembre 2021 à 14h.
Nous recevrons Sergio Valenzuela (Catalan Institute of Nanoscience and Nanotechnology (ICN2), Spain)
"Proximity effects in van der Waals heterostructures”

Résumé :

The isolation of a large variety of two-dimensional materials (2DM) and their co-integration in van der Waals heterostructures has opened new avenues for innovative material design and engineering. In particular, the structural interface quality in the atomically smooth 2DMs allows us to imprint properties of interest in a chosen 2DM by proximity-induced effects. Such an approach is particularly compelling for spintronic devices, which harness their functionality from thin layers of magnetic and non-magnetic materials and their interfaces [1]. In this talk, I will present recent experiments in which we investigate the spin dynamics in graphene-transition metal dichalcogenides heterostructures. I will show that the spin-orbit coupling in graphene can be strongly enhanced by proximity effects. As a consequence, the spin relaxation becomes highly anisotropic, with spin lifetimes that are markedly different depending on the spin orientation [2,3]. I will further demonstrate that the proximity-induced spin-orbit coupling leads to strongly enhanced spin-to-charge interconversion [4]. By performing spin precession experiments in appropriately designed Hall bars, we are able to separate the contributions of the spin Hall and the spin galvanic effects. Remarkably, their corresponding conversion efficiencies can be tailored by electrostatic gating in magnitude and sign, peaking near the graphene charge neutrality point and having a large magnitude even at room temperature.

"Heterostrain determines the flatbands in twisted gaphene layers.”

Le prochain séminaire virtuel du GDR HOWDI aura lieu le mardi 9 novembre 2021 à 14h.
Nous recevrons Vincent Renard (Grenoble, France)
"Heterostrain determines the flatbands in twisted gaphene layers.”

Résumé :

The strongly correlated electron physics recently observed in twisted graphene layers develops in flat bands , which are very sensitive to the relative arrangement between the layers. The twist angle as attracted most of the attention as it is the leading structural parameter. Heterostrain, the in-plane deformation of one layer with respect to the other, is an ubiquitous source of modification of the relative arrangement between the layers which effect has been much less investigated. Performing a detailed meta-analysis of published scanning tunneling microscope data, I will show that heterostrain allows to understand quantitatively the large sample variability observed in experiments in the non interacting limit and raises the question of its influence on strongly correlated electron phases.

"Unveiling excitonic properties of magnons in a quantum Hall ferromagnet."

The next virtual meeting of the GDR HOWDI will be given by Preden Rouleau (CEA) next Tuesday (July 20) at 11h.

"Unveiling excitonic properties of magnons in a quantum Hall ferromagnet."

Zoom connection informations are attached below.

Abstract of the talk :

Magnons enable transferring a magnetic moment or spin over macroscopic distance. In quantum Hall ferromagnets, it has been predicted in the early 90s [1] that spin and charge are entangled, meaning that any change of the spin texture modifies the charge distribution. As a direct consequence of this entanglement, magnons carry an electric dipole moment. Here we report the first evidence of the existence of this electric dipole moment in a graphene quantum Hall ferromagnet [2,3] using a Mach-Zehnder interferometer as a quantum sensor. As magnons propagate towards the interferometer across the insulating bulk, their electric dipole moment modifies the Aharonov-Bohm flux through the interferometer, affecting both the phase and visibility of the interferences. In particular, we relate the phase shift to the sign of this electric dipole moment, the exponential loss of visibility to the flux of emitted magnons, and we show that the magnon emission is a Poissonian process. Finally, we probe the emission energy threshold of the magnons close to filling factor ν=1. For transient states, between ν=0 and ν=1, we observe that the emission energy threshold diminishes towards zero, which might be linked to the emergence of gapless mode predicted in the canted-antiferromagnetic (CAF) phase at ν=0 [4-5]. Being able to couple the spin degree of freedom to an electrostatic potential is a remarkable property of quantum Hall ferromagnets that could be very promising for spintronics.

Millie Dresselhaus died earlier on Monday 20th February at the Mount Auburn Hospital surrounded by her family and other people she loved. Her funeral will be arranged for this Wednesday at MIT (by Jewish tradition this must happen very soon).

We are indebted so much to her for all she has done in the field of graphite and related materials and how she has inspired researches worldwide with an amazing energy and vision during fifty years.

The plan at MIT is to celebrate Millie’s life at a larger gathering in the future. Memorial sessions will be organized at the next Graphene conference 2017 at Bercelona next March at the Conference NT17 in June at Belo Horizonte in Brazil.

The story on the MIT website provides some broad information, in addition to MIT-specific details
