Abstract

In this paper,the structural, electronic and optical properties of Mercury Telluride (HgTe) in hexagonal phase have been studied. The calculations have been performed with pseudopotantial method in density functional theory framework by using Quantum-Espresso package. It can be seen from band structure calculation that the cinnabar phase has semiconducting property. The calculation of the real part of dielectric function leads to refractive index 4.489 for hexagonal phase.
