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…
Strong Single- and Two-Photon Luminescence Enhancement by Nonradiative Energy Transfer across Layered Heterostructure
Medha Dandu, Rabindra Biswas, Sarthak Das +5
The strong light-matter interaction in monolayer transition metal dichalcogenides (TMDs) is promising for nanoscale optoelectronics with their direct band gap nature and the ultra-…
Layer degree of freedom for excitons in transition metal dichalcogenides
Sarthak Das, Garima Gupta, Kausik Majumdar
Layered transition metal dichalcogenides (TMDCs) host a variety of strongly bound exciton complexes that control the optical properties in these materials. Apart from spin and vall…
Inter-layer charge transport controlled by exciton-trion coherent coupling
Sangeeth Kallatt, Sarthak Das, Suman Chatterjee +1
The possibility of electrical manipulation and detection of charged exciton (trion) before its radiative recombination makes it promising for excitonic devices. Using a few-layer g…
