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…
Superconductivity of Cobalt in Thin Films
Nasrin Banu, M. Aslam, Arpita Paul +8
Due to competing long range ferromagnetic order, the transition metals Fe, Co and Ni are not superconductors at ambient pressure. While superconductivity was observed in a non-magn…
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…
Versatile Large-Area Custom-Feature van der Waals Epitaxy of Topological Insulators
Tanuj Trivedi, Anupam Roy, Hema C. P. Movva +4
As the focus of applied research in topological insulators (TI) evolves, the need to synthesize large-area TI films for practical device applications takes center stage. However, c…
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…
