Interband optical transit,ions of Ino.53Gao.\*7As/Ino.s2Alo.48As multi-quantum wells have been clearly observed in photocurrent spectra. Interband transitions were assigned from the spectral structures. Eigen-energies of conduction band were not proportional to the square of quantum numbers. An ele

Interband magneto-photoluminescence (MPL) spectra in n-type InGaAs / InAlAs quantum wells (QWs) lattice-matched to InP were measured between 1.4 and 275 K. From a fan chart of MPL peak energy vs. magnetic field, assignment of Landau levels (LLs) associated with conduction subband (CS) was made consi
