ABSTRACT
Optoelectronic Materials and Pressure Tuning
Optoelectronic materials enable a wide range of technological applications such as photocatalysis, solar cells, light-emitting diodes, lasers, photo detectors, etc. Two main focuses include the understating of the structure-property relationships and the exploration of advanced materials with enhanced and/or emergent functionalities. In this talk, I will present our efforts on the investigation of optoelectronic materials using high pressure, an alternative approach to exploring novel materials with desirable properties which also permit a deeper understanding of a wide range of phenomena. Particularly, using the state-of-the-art high-pressure techniques coupled with in situ synchrotron-based and in-laboratory property measurements, we characterized the changes in the structural, electrical, and optical properties of transition metal oxides and halide perovskites. Pressure-enhanced properties such as higher electron transport and enhanced emission, as well as pressure-induced novel phenomena, were observed.
