Ultrafast energy funneling and lasing kinetics in multiphasic hybrid perovskites (Conference Presentation)
Author(s): Kenan Gundogdu

Paper Abstract

Hybrid organic-inorganic perovskites have been a focus of study due to the impressive performance of methylam- monium lead iodide (MAPI) in photovoltaic (PV) applications. These materials family also provide a new versatile platform for other optoelectronic applications such lasers. In this work we studied exciton dynamics that leads to lasing in various perovskite structures using time resolved absorption, THz conductivity and time resolved photoluminescence experiments. Hybrid perovskite thin films with different morphologies processed to exhibit polycrystalline morphologies with multiphasic nature. These studies reveal the exciton transfer dynamics into lower energy domains, and formation and recombination kinetics of the population inverted state.
