Liquid Epitaxial Growth of GaAsSb and Its Use as a High-Efficiency, Long-Wavelength Threshold Photoemitter

Abstract: The ternary-phase diagram of GaAsSb has been calculated using Darken's quadratic formalism for a ternary liquid and assuming a regular solid solution. Liquid epitaxial layers of GaAsxSb1−x have been grown in the range 0.75>x>1 on {100} and {111} GaAs substrates. Results are in excellent agreement with the calculated phase diagram. Variation of bandgap with composition of the layer has been determined by transmission, photoemission, and x-ray fluorescence experiments. The data were fitted to a cur… Show more

“…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.…”

“…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].…”
