Microcavity polaritonics based on van der Waals heterostructures
Abstract
The objective is to explore a novel platform to realize semiconductor microcavity polaritons. Van der Waals heterostructures based on two-dimensional atomically thin materials, will serve as the matter system that is coupled to a planar distributed Bragg reflector microcavity. The large binding energy exhibited by excitons in two-dimensional semiconductors will enable stable room temperature exciton formation and the realization of novel polaritonic based optoelectronic devices. Specifically, they will fabricate and characterize distributed Bragg reflector microcavities suitable to couple with single layer transition metal dichalcogenide semiconductors. Van der Waals heterostructures including doped tungsten diselenide (WSe2), doped molybdenum disulfide (MoS2), graphene and hexagonal boron nitride (hBN) will enable pn-junction formation and electrical control of excitons via the quantum confined Stark effect. Finally, a device that supports both microcavity polariton formation at room temperature and electrical control will be realized such that this unique platform will enable novel light emitting diode and lasing modalities.
