摘要

Transimisson spectroscopy in lattice matched In0.53Ga0.47As/In0.52Al0.48As multi-quantum wells (MQWs) structures were measured at some low temperatures. Steplike structures accentuated by the exciton peaks of interband transitions were observed in on transimisson specta. Energy of the three light hole transition was lower than one expected with calculation. The lower energy of the three light hole transition might suggest nonparabolisity of the light hole.
