Band gap and lattice constant of GaxIn1−xAsySb1−y
TL;DR: In this paper, the energy band gap and lattice constant of the quaternary alloy GaxIn1−xAsySb1−y were determined over the entire composition space (x, y) using a correlated function expansion (CFE) technique to interpolate from observed ternary compound data.

Theoretical analysis of disorder effects on electronic and optical properties in InGaAsP quaternary alloy
TL;DR: In this article, the effects of structural and chemical disorder on electronic and optical properties of InGaAsP quaternary alloy are studied on the basis of a modified virtual crystal approximation calculated within a simple tight-binding sp3s* theory, which incorporates compositional disorder as an effective potential.
