Physica Scripta | 1987

Excitation Intensity Dependence of Ga1-xAlxAs-GaAs-Superlattice Photoluminescence

H. Weinert; F. Henneberger; Ulrike Woggon; I. N. Uraltsev; H.-G. Bruhl

Experimental results for the excitation intensity dependence of the exciton CW-photoluminescence of GaAs-Ga1-xAlxAs-superlattices for two different values of the well and barrier widths. From a comparison with energy level calculations, conclusions about the gap discontinuities are drawn.
