Tunneling spectroscopy of gate-induced superconductivity in MoS
Davide Costanzo, Haijing Zhang, Bojja Aditya Reddy +2
The ability to gate-induce superconductivity by electrostatic charge accumulation is a recent breakthrough in physics and nano-electronics. With the exception of LaAlO/SrTiO$_3…
Microscopic Origin of the Valley Hall Effect in Transition Metal Dichalcogenides Revealed by Wavelength Dependent Mapping
Nicolas Ubrig, Sanghyun Jo, Marc Philippi +4
The band structure of many semiconducting monolayer transition metal dichalcogenides (TMDs) possesses two degenerate valleys, with equal and opposite Berry curvature. It has been p…
Gate-induced Superconductivity in atomically thin MoS2 crystals
Davide Costanzo, Sanghyun Jo, Helmuth Berger +1
When thinned down to the atomic scale, many layered van der Waals materials exhibit an interesting evolution of their electronic properties, whose main aspects can be accounted for…
Electrostatically Induced Superconductivity at the Surface of WS
Sanghyun Jo, Davide Costanzo, Helmuth Berger +1
We investigate transport through ionic liquid gated field effect transistors (FETs) based on exfoliated crystals of semiconducting WS. Upon electron accumulation, at surface de…
Random strain fluctuations as dominant disorder source for high-quality on-substrate graphene devices
Nuno J. G. Couto, Davide Costanzo, Stephan Engels +6
We have performed systematic investigations of transport through graphene on hexagonal boron nitride (hBN) substrates, together with confocal Raman measurements and a targeted theo…
