The influence of a trap state on the photoluminescence decay times under single pulse excitation
Kuan‐Cheng Chiu
Abstract
Abstract We numerically calculated the time-resolved photoluminescence spectra using the bimolecular trapping-detrapping model. The variations of carrier lifetimes are investigated by changing the carrier recombination and trapping rate constants, as well as the concentration of available trapping states.
