The objective of this research effort is to understand the nonequilibrium dynamics of quasiparticles and polaritons in transition metal dicahcogenides (TMDCs) and their heterostructures. Our work is multidisciplinary. Members of our team fabricate monolayer TMDCs (e.g., WS2, MoSe2, etc.) and other 2D materials (hBN, Graphene) by exfoliation or chemical vapor deposition. Heterostructures and other device geometries are assembled using mechanical transfer techniques. Photonic structures and device contacts are fabricated using lithographic techniques. A wide range of instruments are employed to characterize these materials: photoluminescence mapping, Raman mapping, ellipsometry, AFM, etc. Additional instrumentation resides in the Nanoscience Institute, a shared facility open to researchers on our campus.
