About our Research
Our current research involves the study of functional materials and multidimensional tuning. Most notable among these are the optoelectronic materials, such as metal oxides (TiO2, ZnO, SnO2, etc.), metal dichalcogenides (MoS2, MoSe2, WSe2, their heterojunctions, etc.), and organic-inorganic hybrid materials (halide perovskites). By using state-of-the-art synchrotron-based and in-laboratory probes, we study these systems by examining their interactions with external stimuli, such as pressure, temperature, magnetic field, laser, electromagnetic radiation, etc. Our research also involves the exploration of novel materials under high pressures (giga-Pascal) and/or temperature for energy conversion and storage applications, such as solar cells, LED, lasers, and batteries.
