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…
Origin of selective enhancement of sharp defect emission lines in monolayer WSe on rough metal substrate
Raghav Chaudhary, Varun Raghunathan, Kausik Majumdar
The defect states in atomically thin layers of transition metal dichalcogenides are promising candidates for single photon emission. However, the brightness of such quantum emissio…
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/…
