Abstract
Photoluminescence excitation measurements were performed on GaxIn1−xAsyP1−y/InP single quantum wells. The results were analyzed with a k⋅p approach. Using the effective masses reported in the literature, the ratio of the discontinuities in the conduction and valence band is found to be 35:65. This is in good agreement with a ratio of 37:63, obtained directly from an observed transition involving free holes.Keywords
