Valence band structure with spin–orbit (SO) coupling of GaAs/Ga 1-x Al x As square quantum well (SQW) under the electric field by a calculation procedure based on a finite element method (FEM) is investigated using the multiband effective mass theory ([Formula: see text] method). The validity of the method is confirmed with the results of D. Ahn, S. L. Chuang and Y. C. Chang (J. Appl. Phys.64 (1998) 4056), who calculated valence band structure, using axial approximation for Luttinger–Kohn Hamiltonian and finite difference method. Our results demonstrated that SO coupling and electric field have significant effects on the valence band structure.

AbstractIn this paper, we study the interdiffusion of tensile strained GaAsyPi.y /A10 33Ga0 67As single QW structures with a well width of 60Å. Different P concentrations in the as-grown well are chosen to obtain different tensile strains in the QW. Interdiffusion induces changes in the tensile strains and confinement potentials, which consequently change the valence band structure and the optical gain.

The band structures and optical gain spectra of GaAsSbN/GaAs compressively strained quantum well (QW) were studied using 10-band k.p approach. We found that a higher Sb and N composition in the quantum well and a thicker well give longer emitting wavelength. The result also shows a suitable combination of Sb and N composition, and QW thickness can achieve 1.3 μm lasing. And, the optical gain spectra with different carrier concentrations will be obtained.
