Abstract
Using ab initio pseudopotential method within the local density approximati on we have investigated the electronic properties of SixSn1-x semiconductin g alloy. The bowing parameter of the band-gap energy variation with alloy c oncentration is found to be large. We also analyzed its origin in terms of chemical and structural effects.
