We extend the previous 30-band k· p model effectively employed for relaxed Ge1−xSnx alloy to the case of strained Ge1−xSnx alloy. The strain-relevant parameters for the 30-band k· p model are obtained by using linear interpolation between the values of single crystal of Ge and Sn that are from liter...
