Band Gap Opening in Bilayer Graphene-CrCl/CrBr/CrI van der Waals Interfaces
Giulia Tenasini, David Soler-Delgado, Zhe Wang +10
We report experimental investigations of transport through bilayer graphene (BLG)/chromium trihalide (CrX; X=Cl, Br, I) van der Waals interfaces. In all cases, a large charge t…
Probing magnetism in exfoliated VI layers with magnetotransport
David Soler-Delgado, Feng-rui Yao, Dumitru Dumcenco +6
We perform magnetotransport experiments on VI multilayers, to investigate the relation between ferromagnetism in bulk and in exfoliated layers. The magnetoconductance measured…
Determining the phase diagram of atomically thin layered antiferromagnet CrCl
Zhe Wang, Marco Gibertini, Dumitru Dumcenco +4
Changes in the spin configuration of atomically-thin, magnetic van-der-Waals multilayers can cause drastic modifications in their opto-electronic properties. Conversely, the opto-e…
Spin-flop transition in atomically thin MnPS crystals
Gen Long, Hugo Henck, Marco Gibertini +6
The magnetic state of atomically thin semiconducting layered antiferromagnets such as CrI and CrCl can be probed by forming tunnel barriers and measuring their resistance a…
Intervalley Scattering of Interlayer Excitons in a MoS/MoSe/MoS Heterostructure in High Magnetic Field
Alessandro Surrente, Lukasz Klopotowski, Nan Zhang +9
Degenerate extrema in the energy dispersion of charge carriers in solids, also referred to as valleys, can be regarded as a binary quantum degree of freedom, which can potentially…
Probing the inter-layer exciton physics in a MoS/MoSe/MoS van der Waals heterostructure
