An overview of material properties and the current state of electronic devices based on 2D layered materials is presented. Atomic scale smoothness, varying band alignment and sizeable bandgaps in the single layer limit make this class of materials very interesting for optoelectronic applications. Scaling effects, doping techniques, contacts and strain engineering of 2D materials are discussed. In...
A self-aligned process is developed to couple monolayer WSe2 (30nm × 300nm) to a silver cavity-backed slot-antenna. Optical emission measurements show 340x enhancement in spontaneous emission. Carrier lifetimes of <1ps are measured by streak camera.
