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 -type Ge and confirmed in experiment the PFS…
The theoretical direct-band-gap optical gain of Germanium nanowires
Wen Xiong, Jian-Wei Wang, Wei-Jun Fan +2
We calculate the electronic structures of Germanium nanowires by taking the effective-mass theory. The electron and hole states at the G-valley are studied via the eight-band k.p t…
Band structure of strained GeSn alloy: a full-zone 30-band model
Zhigang Song, Weijun Fan, Chuan Seng Tan +4
We extend the previous 30-band model effectively employed for relaxed GeSn alloy to the case of strained GeSn alloy. The strain-relevant p…
Band structure of GeSnalloy: a full-zone 30-band model
Zhigang Song, Weijun Fan, Chuanseng Tan +4
A full-zone 30-band model is developed as an efficient and reliable tool to compute electronic band structure in GeSn alloy. The model was first used to…
Sharp selective scattering of red, green and blue light achieved via gain material's loss compensation
Yiyang Ye, Rongyue Liu, Zhigang Song +1
For a transparent projection screen based on metallic nanoparticle's localized surface plasmon resonance (LSPR), in the ideal case the metallic nanoparticles dispersed in a transpa…
Prediction of Ideal Triple Degenerate Points in HfIrAs and HfIrBi
Zhi-Gang Song, Claudia Felser, Yan Sun
In this study, two ideal triple degenerate point (TDP) semimetals were predicted, namely, HfIrAs and HfIrBi, that exhibit clean TDPs around the fermi level. At the atomic level, th…
