Nonlinear light absorption by semiconductor microcrystals in a glass matrix
Abstract
A phenomenological theory is proposed for the Burstein-Moss dynamic effect in microcrystals embedded in a glass matrix in the absence of dimensional quantization. The theory allows for radiation intensity distribution over the specimen thickness. The effect of surface recombination on the lifetime of nonequilibrium charge carriers is demonstrated; the recombination rate, the critical microcrystal radius, and microcrystal concentration in the matrix are estimated. The theory is compared against experimental data for CdS(0.1)Se(0.9) microcrystals.
