Magnetization dependent tunneling conductance of ferromagnetic barriers
Autor: Zhe Wang, Ignacio Gutiérrez-Lezama, Dumitru Dumcenco, Nicolas Ubrig, Takashi Taniguchi, Kenji Watanabe, Enrico Giannini, Marco Gibertini, Alberto F. Morpurgo
Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-7 (2021)
Many standard techniques for investigating magnetic properties in the bulk are ill suited to atomically thin van der Waals materials. Here, Wang et al take a prototypical van der Waals ferromagnet, Chromium Bromide, and show how tunneling conductance

Self-sensing, tunable monolayer MoS2 nanoelectromechanical resonators
Autor: Sajedeh Manzeli, Dumitru Dumcenco, Guilherme Migliato Marega, Andras Kis
Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-7 (2019)
Suitable materials for nanoelectromechanical systems should possess excellent mechanical properties and allow displacement self-sensing. Here, the authors fabricate electromechanical resonators based on single-layer MoS2 with electrical readout, oper

Disorder engineering and conductivity dome in ReS2 with electrolyte gating
Autor: Dmitry Ovchinnikov, Fernando Gargiulo, Adrien Allain, Diego José Pasquier, Dumitru Dumcenco, Ching-Hwa Ho, Oleg V. Yazyev, Andras Kis
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-7 (2016)
Rhenium disulphide, ReS2, is a member of the two-dimensional dichalcogenide family. Here, the authors find a suppression of conductivity at high charge density levels in devices with polymer electrolyte gates. The effects of doping and disorder are e

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-9 (2016)
Single-molecule-terminated scanning probes typically operate under ultra-high vacuum conditions at low temperatures. Here, the authors show that tips functionalized with C60 can image single-layer graphene and MoS2with high definition in a liquid env

Band Gap Opening in Bilayer Graphene-CrCl$_3$/CrBr$_3$/CrI$_3$ van der Waals Interfaces
Autor: Giulia Tenasini, David Soler-Delgado, Zhe Wang, Fengrui Yao, Dumitru Dumcenco, Enrico Giannini, Kenji Watanabe, Takashi Taniguchi, Christian Moulsdale, Aitor Garcia-Ruiz, Vladimir I. Fal’ko, Ignacio Gutiérrez-Lezama, Alberto F. Morpurgo
We report experimental investigations of transport through bilayer graphene (BLG)/chromium trihalide (CrX$_3$; X=Cl, Br, I) van der Waals interfaces. In all cases, a large charge transfer from BLG to CrX$_3$ takes place (reaching densities in excess

Probing magnetism in exfoliated VI$_3$ layers with magnetotransport
Autor: David Soler-Delgado, Fengrui Yao, Dumitru Dumcenco, Enrico Giannini, Jiaruo Li, Connor A. Occhialini, Riccardo Comin, Nicolas Ubrig, Alberto F. Morpurgo
We perform magnetotransport experiments on VI$_3$ multilayers, to investigate the relation between ferromagnetism in bulk and in exfoliated layers. The magnetoconductance measured on field-effect transistors and tunnel barriers shows that the Curie t

Quantitative Mapping of the Charge Density in a Monolayer of MoS2 at Atomic Resolution by Off-Axis Electron Holography
Autor: Andras Kis, Robert A. McLeod, Benoit Sklenard, David Cooper, Dumitru Dumcenco, Dmitry Ovchinnikov, Victor Boureau
Publikováno v: ACS Nano. 14:524-530
The electric potential, electric field, and charge density of a monolayer of MoS2 have been quantitatively measured at atomic-scale resolution. This has been performed by off-axis electron holography using a double aberration-corrected transmission e

Recent experiments on van der Waals antiferromagnets have shown that measuring the temperature (T) and magnetic field (H) dependence of the conductance allows their magnetic phase diagram to be mapped. Similarly, experiments on ferromagnetic CrBr3 ba
