Exciton polarization, fine structure splitting and quantum dot asymmetry under uniaxial stress
Ming Gong, Weiwei Zhang, Guang-Can Guo +1
We derive a general relation between the fine structure splitting (FSS) and the exciton polarization angle of self-assembled quantum dots (QDs) under uniaxial stress. We show that…
Atomistic pseudopotential calculations of the optical properties of InAs/InP self-assembled quantum dots
Ming Gong, Weiwei Zhang, Zhuming Han +2
We present a comprehensive study of the optical properties of InAs/InP self-assembled quantum dots (QDs) using an empirical pseudopotential method and configuration interaction tre…
Hidden correlations of exciton complexes in self-assembled quantum dots and rings
Weiwei Zhang, Ming Gong, Chuan-Feng Li +2
The binding energies of trions (, ) and biexciton (XX) in self-assembled semiconductor quantum dots (QDs) are very sensitive to the geometry and chemical composition of t…
Giant optical anisotropy in cylindrical self-assembled InAs/GaAs quantum rings
Weiwei Zhang, Zhiqiang Su, Ming Gong +3
Using a single-particle atomistic pseudopotential method followed by a many-particle configuration interaction method, we investigate the geometry, electronic structure and optical…
