Achieving high transmission of light through a highly conductive structure implemented on a semiconductor remains a challenge in optoelectronics as the transmission is inevitably deteriorated by absorption and Fresnel reflection. There have been nume

We extend the previous 30-band ${k}\cdot{p}$ model effectively employed for relaxed Ge1– x Sn x alloy to the case of strained Ge1– x Sn x alloy. The strain-relevant parameters for the 30-band ${k}\cdot{p}$ model are obtained by using linear inter
