Moiré Excitons in Van der Waals Heterostructures
Kha Tran, Galan Moody, Fengcheng Wu +19
In van der Waals (vdW) heterostructures formed by stacking two monolayer semiconductors, lattice mismatch or rotational misalignment introduces an in-plane moiré superlattice. Whil…
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…
Detection of current induced spin polarization in epitaxial BiTe thin film
Rik Dey, Anupam Roy, Tanmoy Pramanik +5
We electrically detect charge current induced spin polarization on the surface of molecular beam epitaxy grown BiTe thin film in a two-terminal device with a ferromagnetic…
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…
High-Mobility Holes in Dual-Gated WSe Field-Effect Transistors
Hema C. P. Movva, Amritesh Rai, Sangwoo Kang +6
We demonstrate dual-gated -type field-effect transistors (FETs) based on few-layer tungsten diselenide (WSe) using high work-function platinum source/drain contacts, and a h…
Theoretical and experimental investigation of vacancy-based doping of monolayer MoS on oxide
Amithraj Valsaraj, Jiwon Chang, Amritesh Rai +2
Monolayer transition metal dichalcogenides are novel, gapped two-dimensional materials. Toward device applications, we consider MoS layers on dielectrics, in particular in this…
