Calculation of Direct E0 energy gaps for III-V-Bi alloys using Quantum Dielectric Theory

Abstract

A mathematical model based on Quantum Dielectric Theory has been used to calculate the direct E0 energy gaps of bismuth containing ternary alloys. The variation of E0 with x for InSb1-xBix and GaSb1-xBix are in good agreement with the experimental results. The composition dependence of E0 at different temperatures is also found out for some other ternary alloys like InPBi and AlSbBi.
