  • High-pressure and low-temperature studies on lead-free halide perovskites

I have been working on lead-free halide perovskites under pressure and temperature. I try to tune the structural, optical, and electronic properties by applying pressure and temperature without changing the material compositions. My experimental studies include Raman scattering, photoluminescence, and synchrotron x-ray diffraction. I have just started to learn density functional theory.
