摘要：
A series of interband optical transitions associated with exciton absorptions have been observed in photocurrent spectra of p-i-n junctions including InGaAs/InAlAs multi-quantum wells with well widths of 5 and 10 nm. Eigen energies with consecutive quantum numbers were determined for conduction electrons and heavy holes. The energies were dependent on the square of the respective quantum numbers. The possible ranges of effective masses and band offsets were analyzed using a simple paricle-in-a-box calculation.
