Electron-hole diffusion lengths > 175 μm in solution-grown CH3NH3PbI3 single crystals
TL;DR: It is found that the diffusion lengths in CH3NH3PbI3 single crystals grown by a solution-growth method can exceed 175 micrometers under 1 sun (100 mW cm−2) illumination and exceed 3 millimeters under weak light for both electrons and holes.
Journal ArticleDOI
Sensitive X-ray detectors made of methylammonium lead tribromide perovskite single crystals
Haotong Wei,Yanjun Fang,Yanjun Fang,Padhraic Mulligan,William Chuirazzi,Hong-Hua Fang,Congcong Wang,Benjamin Ecker,Yongli Gao,Yongli Gao,Maria Antonietta Loi,Lei Cao,Jinsong Huang +12 more
TL;DR: In this paper, single-crystal perovskite devices 2-3 mm thick exhibit 16.4% X-ray detection efficiency with sensitivity four times higher than α-Se detectors.
Journal ArticleDOI
Monolithic integration of hybrid perovskite single crystals with heterogenous substrate for highly sensitive X-ray imaging
Wei Wei,Yang Zhang,Qiang Xu,Haotong Wei,Yanjun Fang,Qi Wang,Yehao Deng,Tao Li,Alexei Gruverman,Lei Cao,Jinsong Huang +10 more
TL;DR: In this paper, hybrid perovskite crystals are integrated onto silicon wafers enabling fabrication of an X-ray linear detector array, which may reduce patient dose in medical imaging applications.
Journal ArticleDOI
Dopant compensation in alloyed CH 3 NH 3 PbBr 3-x Cl x perovskite single crystals for gamma-ray spectroscopy
Haotong Wei,Dylan DeSantis,Wei Wei,Yehao Deng,Dengyang Guo,Tom J. Savenije,Lei Cao,Jinsong Huang,Jinsong Huang +8 more
TL;DR: A dopant compensation in alloyed OIHP single crystals is reported to overcome limitations of device noise and charge collection, enabling γ-ray spectrum collection at room temperature.
Journal ArticleDOI

Hantian Gao,Shreyas Muralidharan,Nicholas Pronin,Rezaul Karim,Susan M. White,Thaddeus J. Asel,G. M. Foster,Sriram Krishnamoorthy,Siddharth Rajan,Lei Cao,Masataka Higashiwaki,Holger von Wenckstern,Marius Grundmann,Hongping Zhao,David C. Look,Leonard J. Brillson +15 more
TL;DR: In this article, the authors used depth-resolved cathodoluminescence spectroscopy and surface photovoltage spectrography to measure the effects of near-surface plasma processing and neutron irradiation on native point defects in β-Ga2O3.
