Electroluminescence from indirect band gap semiconductor ReS
Ignacio Gutiérrez Lezama, Bojja Aditya Reddy, Nicolas Ubrig +1
It has been recently claimed that bulk crystals of transition metal dichalcogenide (TMD) ReS are direct band gap semiconductors, which would make this material an ideal candida…
Direct Observation of Long-range field-effect from gate tuning of non-local conductivity
Lin Wang, Ignacio Gutiérrez-Lezama, Céline Barreteau +3
We report the observation of an unexpected, long-range field-effect in WTe devices, leading to large gate-induced changes of the transport properties of crystals much thicker t…
Ambipolar Light-Emitting Transistors on Chemical Vapor Deposited Monolayer MoS2
Evgeniy Ponomarev, Ignacio Gutiérrez-Lezama, Nicolas Ubrig +1
We realize and investigate ionic liquid gated field-effect transistors (FETs) on large-area MoS2 monolayers grown by chemical vapor deposition (CVD). Under electron accumulation, t…
