Ultraviolet‐Visible‐Short‐Wavelength Infrared Broadband and Fast‐Response Photodetectors Enabled by Individual Monocrystalline Perovskite Nanoplate (Small 37/2023)

Individual Perovskite Nanoplate Photodetectors In article number 2301386, Lu Zhu, Shenghuang Lin, Haoran Mu, Zhanfeng Huang, and co-workers design and fabricate an individual monocrystalline MAPbBr3 nanoplate-based photodetector that simultaneously achieves efficient ultraviolet-visible-short-wavelength infrared broadband photodetection and fast-response. They find that perovskites with relatively large bandgap can achieve infrared response even in short-wavelength infrared wavelength via surface trap assisted sub-bandgap absorption of MAPbBr3 nanoplate. This work highlights the potential of perovskite-based broadband photodetection and stimulates the monolithic integration of various micro/nano- perovskite-based devices.
