Perovskite light-emitting diodes based on spontaneously formed submicrometre-scale structures
Yu Cao,Nana Wang,He Tian,Jingshu Guo,Yingqiang Wei,Hong Chen,Yanfeng Miao,Wei Zou,Kang Pan,Yarong He,Hui Cao,You Ke,Mengmeng Xu,Ying Wang,Ming Yang,Kai Du,Zewu Fu,Decheng Kong,Daoxin Dai,Yizheng Jin,Gongqiang Li,Hai Li,Qiming Peng,Jianpu Wang,Wei Huang,Wei Huang,Wei Huang +26 more
TL;DR: The formation of submicrometre-scale structure in perovskite light-emitting diodes can raise their external quantum efficiency beyond 20%, suggesting the possibility of both high efficiency and high brightness.
Journal ArticleDOI
Passivated Single-Crystalline CH3NH3PbI3 Nanowire Photodetector with High Detectivity and Polarization Sensitivity
Liang Gao,Kai Zeng,Jingshu Guo,Cong Ge,Jing Du,Yang Zhao,Chao Chen,Hui Deng,Yisu He,Haisheng Song,Guangda Niu,Jiang Tang +11 more
TL;DR: This work solves this key problem by introducing oleic acid soaking to passivate surface defects of CH3NH3PbI3 nanowires, which leads to a device with much improved stability and unprecedented sensitivity (measured detectivity of 2 × 1013 Jones).
Journal ArticleDOI

High-speed and high-responsivity hybrid silicon/black-phosphorus waveguide photodetectors at 2 {\mu}m
Yanlong Yin,Rui Cao,Jingshu Guo,Chaoyue Liu,Jiang Li,Xianglian Feng,Huide Wang,Wei Du,Akeel Qadir,Han Zhang,Yungui Ma,Shiming Gao,Yang Xu,Yaocheng Shi,Limin Tong,Daoxin Dai +15 more
TL;DR: In this paper, two-dimensional materials (i.e., black-phosphorus (BP) thin films with optimized medium thicknesses (~40 nm) are introduced as the active material for light absorption and silicon/BP hybrid ridge waveguide photodetectors are demonstrated with a high responsivity at a low bias voltage.
