Energy band gap characteristics of GaP1−xBix calculated using Quantum Dielectric Theory and Valence Band Anticrossing model

Abstract

Mathematical models based on Quantum Dielectric Theory(QDT) and Valence Band Anticrossing (VBAC) interaction have been used to explain the composition dependence of band gap for GaP1-xBix. The theoretically predicted bandgap of GaBi using QDT is used to calculate the band structure for the ternary alloy.
