Strain effects on Phase-Filling Singularities in Highly Doped n-Type Ge

Zhigang Song, Wei-Jun Fan, C. S. Tan +4

Recently, Chi Xu et al. predicted the phase-filling singularities (PFS) in the optical dielectric function (ODF) of the highly doped $n$ -type Ge and confirmed in experiment the PFS…

Band structure of strained Ge $_{1 - x}$ Sn $_{x}$ alloy: a full-zone 30-band $k \cdot p$ model

Zhigang Song, Weijun Fan, Chuan Seng Tan +4

We extend the previous 30-band $k$ $\cdot$ $p$ model effectively employed for relaxed Ge $_{1 - x}$ Sn $_{x}$ alloy to the case of strained Ge $_{1 - x}$ Sn $_{x}$ alloy. The strain-relevant p…

Band structure of Ge $_{1 - x}$ Sn $_{x}$ alloy: a full-zone 30-band $k$ $\cdot$ $p$ model

Zhigang Song, Weijun Fan, Chuanseng Tan +4

A full-zone 30-band $k$ $\cdot$ $p$ model is developed as an efficient and reliable tool to compute electronic band structure in Ge $_{1 - x}$ Sn $_{x}$ alloy. The model was first used to…
