A full-zone 30-band k · p model is developed as an efficient and reliable tool to compute electronic band structure in Ge1−xSnx alloy. The model was first used to reproduce the electronic band structures in Ge and α-Sn obtained with empirical tight binding and ab initio methods. Input parameters for...
