Application of band theory to experimental eigen-state energies of un-doped InGaAs quantum wells lattice-matched to InP
Nonparabolic subband structure of InGaAs/InAlAs quantum wells (QWs) was studied theoretically and experimentally. In this paper, nonparabolic effective masses of electrons and band offset of InAlAs barriers were experimentally deduced from eigen-states of conduction subbands confined within the two-dimensional InGaAs QWs. As the dispersion relations for electron, light hole and hole subbands were obtained using the envelope function approximation taking into account band nonparabolicity, a simple way to design was proposed.
