The main goal of this project is to understand the effects of interlayer coupling in heterostructures of two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs) and use this knowledge to form structures and devices with desired optical response. The intrinsic semiconducting character of many TMDs, direct band gap in monolayer limit and suppressed screening effect in atomically thin form, makes these materials ideal building blocks for developing optoelectronic applications, including photodetectors, photodiodes, light-emitting devices, and photovoltaic cells. The major experimental effort in this project will be a development of capabilities to measure specific optical response via reflectivity, photoluminescence and Raman spectroscopy measurements. The optical response measurements will be directly correlated to the interlayer coupling in heterostructures. The optical response will be also investigated by pump-probe measurements.
