Journal ArticleDOI
Superior Optical Properties of Perovskite Nanocrystals as Single Photon Emitters.
Fengrui Hu,Huichao Zhang,Huichao Zhang,Chun Sun,Chunyang Yin,Bihu Lv,Chunfeng Zhang,William W. Yu,Xiaoyong Wang,Yu Zhang,Min Xiao,Min Xiao +11 more
TL;DR: The observation of single photon emission from single CsPbBr3 perovskite nanocrystals (NCs) synthesized from a facile colloidal approach is reported, paving the way toward quantum-light applications of perovSKite NCs in various quantum information processing schemes.
Journal ArticleDOI
Probing Carrier Transport and Structure-Property Relationship of Highly Ordered Organic Semiconductors at the Two-Dimensional Limit.
Yuhan Zhang,Jingsi Qiao,Si Gao,Fengrui Hu,Daowei He,Bing Wu,Ziyi Yang,Bingchen Xu,Yun Li,Yi Shi,Wei Ji,Wei Ji,Peng Wang,Xiaoyong Wang,Min Xiao,Min Xiao,Hangxun Xu,Jianbin Xu,Jianbin Xu,Xinran Wang +19 more
TL;DR: It is found that the charge transport is dominated by hopping in the first conductive layer, but transforms to bandlike in subsequent layers, attributed to strong modulation of the molecular packing by interfacial vdW interactions, as corroborated by quantitative structural characterization and density functional theory calculations.
Journal ArticleDOI
Imaging exciton–polariton transport in MoSe2 waveguides
Fengrui Hu,Fengrui Hu,Y. Luan,Y. Luan,Marie Scott,Jiaqiang Yan,Jiaqiang Yan,D. G. Mandrus,D. G. Mandrus,Xiaodong Xu,Zhe Fei,Zhe Fei +11 more
TL;DR: In this article, a nano-optical imaging study of waveguide EPs in MoSe2, a prototypical van der Waals (vdW) semiconductor, was performed.
Journal ArticleDOI
Slow Auger Recombination of Charged Excitons in Nonblinking Perovskite Nanocrystals without Spectral Diffusion
Fengrui Hu,Chunyang Yin,Huichao Zhang,Huichao Zhang,Chun Sun,William W. Yu,Chunfeng Zhang,Xiaoyong Wang,Yu Zhang,Min Xiao,Min Xiao +10 more
TL;DR: It is shown that nonblinking PL is readily available in the newly synthesized perovskite CsPbI3 NCs and that their Auger recombination of charged excitons is greatly slowed down, as signified by a PL lifetime about twice shorter than that of neutral excitONS.
Journal ArticleDOI
Bright-Exciton Fine-Structure Splittings in Single Perovskite Nanocrystals
Chunyang Yin,Liyang Chen,Nan Song,Yan Lv,Fengrui Hu,Chun Sun,William W. Yu,Chunfeng Zhang,Xiaoyong Wang,Yu Zhang,Min Xiao,Min Xiao +11 more
TL;DR: The above findings have prepared an efficient platform suitable for probing exciton and spin dynamics of semiconductor nanostructures at the visible-wavelength range, from which a variety of practical applications such as in entangled photon-pair source and quantum information processing can be envisioned.
