Covalent Nitrogen Doping in Molecular Beam Epitaxy-Grown and Bulk WSe₂
(American Institute of Physics Inc, 2018-10-22)
Covalent p-type doping of WSe₂ thin films grown by molecular beam epitaxy and WSe₂ exfoliated from bulk crystals is achieved via remote nitrogen plasma exposure. X-ray photoelectron and Raman spectroscopies indicate ...
Nucleation and Growth of WSe₂: Enabling Large Grain Transition Metal Dichalcogenides
(IOP Publishing Ltd, 2017-09-22)
The limited grain size (< 200 nm) for transition metal dichalcogenides (TMDs) grown by molecular beam epitaxy (MBE) reported in the literature thus far is unsuitable for high-performance device applications. In this work, ...
Oxidation of GaSb(100) and its Control Studied by Scanning Tunneling Microscopy and Spectroscopy
Atomic-scale knowledge and control of oxidation of GaSb(100), which is a potential interface for energy-efficient transistors, are still incomplete, largely due to an amorphous structure of GaSb(100) oxides. We elucidate ...
