摘要

A comparative luminescence study of two Ga/sub 0.52/In/sub 0.48/P-(Al/sub 0.5/Ga/sub 0.5/)/sub 0.52/In/sub 0.48/P single-quantum-well (SQW) samples with bulk and multiquantum barrier (MQB) barriers is presented. When excess carriers are only created in the quantum wells (QW's) of the samples by resonant excitation using a dye laser, the luminescence efficiency of both samples as a function of temp...
