Abstract
By use of homogeneously excited small mesa structures a highly uniform electron-hole plasma (EHP) is created by cw excitation of As/InP single-quantum-well (SQW) structures. Because of the high homogeneity of the EHP in space and time we observe many-body effects and band filling under very clear experimental conditions. Our luminescence measurements demonstrate the subband dependence of the band-gap renormalization and a strong dependence of the band-gap reduction on the width of the As/InP SQW’s.
