Paper Abstract

The electronics structures of the Ga1-xINxNyAs1-y/GaAs compressive strained quantum wells(QWs) are investigated using 6x6 kxp Hamiltonian including the heavy hole, light hole and spin-orbit splitting band. By varying the well width and mole fraction of N in the well material, the effects of quantum confinement and compressive strain are examined. The curves of dependence of transition energy on well width and N mole fraction are obtained. The valence subband energy dispersion curves, density of states, TE and TM squared optical transition matrix elements and optical gain spectra of three possible quantum well structures for emitting 1.3micrometers wavelength are given.
