Abstract

Electronic band structure of GaInNAs/GaAs multi-quantum wells was investigated using photoluminescence excitation spectroscopy. The experimental spectra showed clear excitonic features, and the transition energies were compared with theoretical calculations. The valence band was obtained by solving Luttinger-Kohn Hamiltonian using a standard approach which took into account the strain effect. It was found that the coupling strength differed between the quantum states in quantum wells.
