We fabricate, pattern, and contact 2D materials such as graphene, monolayer transition metal dichalcogenides (TMDs) and monolayer hexagonal boron nitride (hBN).We than explore the effects of ultra-strong electrical fields, mechanical strain, chemical intercalation and functionalization of 2D materials. Our goal is to discover new electronic phases, phase transitions, and to ultimately control the Hamiltonians of 2D materials. We also seek applications of resulting systems in quantum electronics, sensing, and photoconversion. Our main experimental tools are nanofabrication (we run a dedicate cleanroom with nanofabrication equipment), low temperature electrical transport, optoelectronics, and nanomechanics measurements. We also like to build setups that miniaturize complex experimental tools on a single nanofabricated chip. For example, we develop technologies to cut, apply mechanical strain, deposit molecules on atom-thick 2D materials, in vacuum and at cryogenic temperatures.
