Sensing the local magnetic environment through optically active defects in a layered magnetic semiconductor
Julian Klein, Zhigang Song, Benjamin Pingault +14
Atomic-level defects in van der Waals (vdW) materials are essential building blocks for quantum technologies and quantum sensing applications. The layered magnetic semiconductor Cr…
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…
Non-Superconducting Non-Abelian Statistics in One-Dimensional Topological Insulators
Zhigang Song
Topological materials are of great interest for applications in quantum computing, providing intrinsic robustness against environmental noises. A popular direction is to look for M…
Temperature-dependent Optoelectronic Properties of Quasi-2D Colloidal Cadmium Selenide Nanoplatelets
Sumanta Bose, Sushant Shendre, Zhigang Song +5
Colloidal Cadmium Selenide (CdSe) nanoplatelets (NPLs) are a recently developed class of efficient luminescent nanomaterial suitable for optoelectronic device applications. A chang…
Atomic-ordering-induced quantum phase transition between topological crystalline insulator and Z2 topological insulator
Hui-Xiong Deng, Zhi-Gang Song, Shu-Shen Li +2
Topological phase transition in a single material usually refers to transitions between a trivial band insulator and a topological Dirac phase, but the transition may also occur be…
Resonant impurities states-driven topological transition in quantum well
Zhi-Gang Song, Wei-Jun Fan, Yan-Yang Zhang +1
We demonstrate theoretically that a new system quantum well can realize the topological transition based on the 16-band kp model. Utilizing the strain introduced by the doped impur…
Route towards Localization for Quantum Anomalous Hall Systems with Chern Number 2
Zhi-Gang Song, Yan-Yang Zhang, Jun-Tao Song +1
The quantum anomalous Hall system with Chern number 2 can be destroyed by sufficiently strong disorder. During its process towards localization, it was found that the electronic st…
