Highly tunable layered exciton in bilayer WS: linear quantum confined Stark effect versus electrostatic doping
Sarthak Das, Medha Dandu, Garima Gupta +6
In 1H monolayer transition metal dichalcogenide, the inversion symmetry is broken, while the reflection symmetry is maintained. On the contrary, in the bilayer, the inversion symme…
Anomalous Stark Shift of Excitonic Complexes in Monolayer Semiconductor
Nithin Abraham, Kenji Watanabe, Takashi Taniguchi +1
Monolayer transition metal dichalcogenide semiconductors host strongly bound two-dimensional excitonic complexes, and form an excellent platform for probing many-body physics throu…
Astability versus Bistability in van der Waals Tunnel Diode for Voltage Controlled Oscillator and Memory Applications
Nithin Abraham, Krishna Murali, Kenji Watanabe +2
Van der Waals (vdW) tunnel junctions are attractive due to their atomically sharp interface, gate tunablity, and robustness against lattice mismatch between the successive layers.…
Unified benchmarking and characterization protocol for nanomaterial-based heterogeneous photodetector technologies
Nithin Abraham, Kausik Majumdar
Over the last few years, there has been a rapid growth towards demonstrating highly sensitive, fast photodetectors using photoactive nano-materials. As with any other developing an…
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…
