Liying Zhang,Xiangqian Xiu,Li Yuewen,Yuxia Zhu,Hua Xuemei,Zili Xie,Tao Tao,Bin Liu,Peng Chen,Rong Zhang,Youdou Zheng +10 more
TL;DR: In this article, a metal-semiconductor-metal structured solar-blind photodetector (PD) has been fabricated by depositing interdigital Ti/Au electrodes on the nanowire arrays.
Journal ArticleDOI
Large-scale fabrication and luminescence properties of GaN nanostructures by a soft UV-curing nanoimprint lithography.
Zhe Zhuang,Xu Guo,Guogang Zhang,Bin Liu,Rong Zhang,Ting Zhi,Tao Tao,Haixiong Ge,Fang-Fang Ren,Zili Xie,Youdou Zheng +10 more
TL;DR: According to finite-difference time-domain simulations and cathodoluminescence mappings, it is concluded that the enhancement for nanorods is due to the improvements of both spontaneous emission rate and light extraction efficiency caused by periodic GaN structures on the surface.
Journal ArticleDOI
Great enhancement in the excitonic recombination and light extraction of highly ordered InGaN/GaN elliptic nanorod arrays on a wafer scale
Zhe Zhuang,Xu Guo,Bin Liu,Fengrui Hu,Jiangping Dai,Y. Zhang,Y. Zhang,Yi Li,Tao Tao,Ting Zhi,Zili Xie,Haixiong Ge,Xiaoyong Wang,Min Xiao,Tao Wang,Tao Wang,Yi Shi,Youdou Zheng,Rong Zhang +18 more
TL;DR: It is demonstrated that elliptic NR arrays improve the light extraction greatly and have polarized emission, both of which possibly result from the broken structure symmetry.
Journal ArticleDOI
Localized surface plasmon enhanced Ga2O3 solar blind photodetectors.
Ruifan Tang,Guanqi Li,Cheng Li,Jinchai Li,Yanfang Zhang,Kai Huang,Jiandong Ye,Junyong Kang,Rong Zhang,Youdou Zheng +9 more
TL;DR: These findings provide direct evidence for Rh plasmonic enhancement in solar-blind spectral region, offering an alternative pathway for the rational design of high-performance solar- blind PDs.
Journal ArticleDOI
Precipitation of Cu and Fe in Dislocated Floating-Zone-Grown Silicon
TL;DR: In this paper, the authors investigated the precipitation behavior of Cu and Fe in dislocated floating-zone-grown silicon crystals by means of transmission electron microscopy and the electron-beam-induced-current (EBIC) technique.
