Recently, there is a renaissance of halide perovskites as a class of semiconductor materials for a variety of photovoltaics and optoelectronics. Particularly, the inorganic halide perovskites draw more and more attention, owing to their enhanced stability toward moisture, oxygen, and heat, compared to the organic-inorganic hybrid perovskites (e.g. methylammonium lead iodide). The controlled synthesis, detailed structural analysis, optical, and electronic properties are of great fundamental interest. This project currently focuses on the synthesis of inorganic halide perovskite nanostructures and the characterization of their physical properties to 1) advance synthetic methodology of 0D, 1D, and 2D nanostructures, 2) establish and advance technology and instrumentation to study fundamental nanomaterial properties as well as the physical, chemical, and electronic interactions between them, and 3) apply the extracted knowledge to both develop integrated optoelectronic and photonic devices from these building blocks and to feed this knowledge back into the virtuous cycle of design, synthesis, measurement and application.
