“…Direct-gap bowing parameters in the range 1.0-1.2 eV have been determined by a number of workers from absorption measurements. [530][531][532][533][534][535] It was noted in the first study 536 of epitaxial GaAs 0.5 Sb 0.5 on InP in 1984 that the apparent band gap of 0.804-0.807 eV was smaller than that implied by previously determined bowing parameters. [537][538][539] Recently, a low-temperature E g ⌫ of 0.813 eV was measured by Merkel et al 540 and Hu et al, 541 and its temperature dependence was obtained.…”

, along with their ternary and quaternary alloys. Based on a review of the existing literature, complete and consistent parameter sets are given for all materials. Emphasizing the quantities required for band structure calculations, we tabulate the direct and indirect energy gaps, spin-orbit, and crystal-field splittings, alloy bowing parameters, effective masses for electrons, heavy, light, and split-off holes, Luttinger parameters, interband momentum matrix elements, and deformation potentials, including temperature and alloy-composition dependences where available. Heterostructure band offsets are also given, on an absolute scale that allows any material to be aligned relative to any other.

“…for a pseudo-regular solution model with an interaction parameter varying linearly with temperature have given good results in some cases [3], [4]. The more general quasi-chemical equilibrium model with temperature-independent interchange energy leads to a satisfactory representation of the binary and ternary phase diagrams for some metallic systems [5] and for combinations of elements from group III, IV and V [6], [7], [8].…”

To cite this version:A. Laugier. Thermodynamics and phase diagram calculations in II-VI and IV-VI ternary systems using an associated solution model. Revue de Physique Appliquee, 1973, 8 (3) Abstract. 2014 The thermodynamic properties and the T-x phase diagrams for liquid-solid equilibrium in II-VI and IV-VI ternary systems are described by a regular associated liquid solution model derived from that used by Jordan for ZnTe and CdTe and by the regular approximation for the solid solution. For the pseudo-binary systems exhibiting miscibility in both phases and monotonic variation of the liquidus and solidus curves, a general expression is obtained. It is independent of the interactions in the liquid, and is the same as for ideal non associated liquids. In the calculation of the ternary T-x phase diagrams five parameters are needed : the two interaction parameters 03B11, 03B12, the two coefficients of dissociation, 03B21, 03B22, obtained from the respective binary liquidus, and the interaction parameter W in the solid, derived from the pseudo-binary phase diagrams. Good agreement with experimental data is obtained for the pseudo-binary systems : ZnTe-CdTe, ZnTe-HgTe, ZnSe-ZnTe, CdTe-HgTe, CdTe-CdSe, HgTe-HgSe, PbSe-PbTe, PbTe-SnTe, and for the ternary systems : Zn-Cd-Te and Pb-Sn-Te. The theory is especially suited for the case 03B2 ~ 0 and 03B1 is small. It is applied to the calculation of the chalcogen-rich part of the ternary systems : Cd-Hg-Te and Cd-Se-Te.

Abstract. (Ga,In)As/GaAs/Ga(As,Sb) multi-quantum well heterostructures have been investigated using continuous wave and time-resolved photoluminescence spectroscopy at various temperatures. A complex interplay was observed between the excitonic type-II transitions with electrons in the (Ga,In)As well and holes in the Ga(As,Sb) well and the type-I excitons in the (Ga,In)As and Ga(As,Sb) wells. The type-II luminescence exhibits a strongly non-exponential temporal behavior below a critical temperature of T c = 70 K. The transients were analyzed in the framework of a rate-equation model. It was found that the exciton relaxation and hopping in the localized states of the disordered ternary Ga(As,Sb) are the decisive processes to describe the dynamics of the type-II excitons correctly.
