Observation of coupling between zero- and two-dimensional semiconductor systems based on anomalous diamagnetic effects
Shuo Cao,Jing Tang,Yue Sun,Kai Peng,Yunan Gao,Yanhui Zhao,Chenjiang Qian,S. S. Sun,Hassan Ali,Yuting Shao,Shiyao Wu,Feilong Song,David A. Williams,Weidong Sheng,Kuijuan Jin,Xiulai Xu +15 more
TL;DR: In this paper, the authors reported the direct observation of coupling between a single self-assembled InAs quantum dot and a wetting layer, based on strong diamagnetic shifts of many-body exciton states using magneto-photoluminescence spectroscopy.
Richardson-Schottky transport mechanism in ZnS nanoparticles
Hassan Ali,Hassan Ali,Usman Khan,Muhammad Rafiq,Attia Falak,Adeela Narain,Tang Jing,Xiulai Xu +7 more
TL;DR: In this article, the synthesis and electrical transport mechanism in ZnS semiconductor nanoparticles was investigated for temperature ranging from 300 K to 400 K. The experimental value of barrier lowering coefficient βexp lies close to the theoretical value of Richardson-Schottky and Poole-Frenkel barrier lowering coefficients.
