Excited State Properties of Two-Dimensional Lead Halide Perovskites
My research focus is in examining the electronic environment of two-dimensional lead halide perovskites. Lead halide perovskites are an emerging material field in solar cells, LEDs, and other optoelectronic devices. By chemically engineering the stochiometry of the perovskite structure, electronically isolated monolayers can be formed in which diffusion is limited to a single plane. Current studies involve examing the evolving environment of mixed halide perovskites using transient absorption spectroscopy and density functional theory. The aim is to improve the selection of materials of for optoelectronic applications by establishing a more complete view of the evolution of excited state carriers.
