✦ Synopsis

We have determined the pressure dependence of the direct bandgap, ionicity, transverse effective charge and refractive index for CdTe. The study is performed using the sp 3 s * semi-empirical tight-binding method with the scaling law and Murnaghan's equation of state. All these properties were found to have a sublinearity behaviour with the pressure. The results are compared with other works.

We present first-principles full-potential linearized augmented plane wave calculations of the effect of hydrostatic pressure on the optical properties of wurtzite GaN, InN and AlN compounds. The refractive index and its variation with hydrostatic pressure are well described. The accurate calculatio
