摘要：

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