Structural and Optical Properties of AlAsxSb1-x

We present a theoretical investigation of the structural and optical properties of AlAsxSb1-x semiconducting alloys in zinc-blende structure based on the empirical pseudopotential method within the virtual crystal approximation combined with the Harrison bond-orbital model. The Elastic Constant, bulk modulus, refractive index, high frequency dielectric constant, static dielectric constant are calculated for AlAsxSb1-x. Our results for AlAsxSb1-x (0<x<1) are predictions.
