Gate-tunable trion switch for excitonic device applications
Sarthak Das, Sangeeth Kallatt, Nithin Abraham +1
Trions are excitonic species with a positive or negative charge, and thus, unlike neutral excitons, the flow of trions can generate a net detectable charge current. Trions under fa…
Highly Sensitive, Fast Graphene Photodetector with Responsivity A/W Using Floating Quantum Well Gate
Krishna Murali, Nithin Abraham, Sarthak Das +2
Graphene, owing to its zero bandgap electronic structure, is promising as an absorption material for ultra-wideband photodetection applications. However, graphene-absorption based…
Gate tunable WSe2/SnSe2 backward diode with ultrahigh reverse rectification ratio
Krishna Murali, Medha Dandu, Sarthak Das +1
Backward diodes conduct more efficiently in the reverse bias than in the forward bias, providing superior high frequency response, temperature stability, radiation hardness, and 1/…
