Multi-body interactions and carrier dynamics in WSe2 for high-performance quantum-enabled devices
Abstract
The discovery of graphene has ignited intense interest in two-dimensional layered materials (2DLMs) which has fueled research at the atomic and molecular limit in these exotic materials. Monolayers of these materials were first mechanically exfoliated from the bulk crystals using scotch-tape to pry-apart the weak interlayer van der Waals bonds, while synthetic routes are also gaining momentum. Within the 2DLMs family, the transition metal dichalcogenides (TMDCs), such as MoS2, MoSe2, WS2 and WSe2, exhibit indirect-to-direct optical transitions in going from the bulk semiconducting crystals to monolayers. Recent studies have shown their exciting potential in ultra-thin transistor platforms, tunable photovoltaics, and as light emitters. In this proposal, we will leverage our highly encouraging preliminary data on pristine crystalline quality WSe2 synthesized in-house using chemical vapor deposition to complete a number of studies of structure and properties.
