Accelerated Carrier Recombination by Grain Boundary/Edge Defects in MBE Grown Transition Metal Dichalcogenides
Ke Chen, Anupam Roy, Amritesh Rai +5
Defect-carrier interaction in transition metal dichalcogenides (TMDs) play important roles in carrier relaxation dynamics and carrier transport, which determines the performance of…
Carrier Trapping by Oxygen Impurities in Molybdenum Diselenide
Ke Chen, Anupam Roy, Amritesh Rai +7
Understanding defect effect on carrier dynamics is essential for both fundamental physics and potential applications of transition metal dichalcogenides. Here, the phenomenon of ox…
Impact of Junction Depth and Abruptness on the Activation and the Leakage Current in Germanium n/p Junctions
William Hsu, Amritesh Rai, Xiaoru Wang +3
The phosphorous activation in Ge n/p junctions is compared in terms of junction depth, by using laser spike annealing at 860°C for 400s. The reverse junction leakage is fo…
Angular dependence of magnetization reversal in epitaxial chromium telluride thin films with perpendicular magnetic anisotropy
Tanmoy Pramanik, Anupam Roy, Rik Dey +5
We investigate magnetic anisotropy and magnetization reversal mechanism in chromium telluride thin films grown by molecular beam epitaxy. We report existence of strong perpendicula…
Intra-Domain Periodic Defects in Monolayer MoS
Anupam Roy, Rudresh Ghosh, Amritesh Rai +8
We present an ultra-high vacuum scanning tunneling microscopy (STM) study of structural defects in molybdenum disulfide thin films grown on silicon substrates by chemical vapor dep…
Air Stable Doping and Intrinsic Mobility Enhancement in Monolayer by Amorphous Encapsulation
Amritesh Rai, Amithraj Valsaraj, Hema C. P. Movva +12
To reduce Schottky-barrier-induced contact and access resistance, and the impact of charged impurity and phonon scattering on mobility in devices based on 2D transition metal dicha…
