High-sensitive and fast response to 255 nm deep-UV light of CH(3)NH(3)PbX(3) (X = Cl, Br, I) bulk crystals

Deep-UV light detection has important application in surveillance and homeland security regions. CH(3)NH(3)PbX(3) (X = Cl, Br, I) materials have outstanding optical absorption and electronic transport properties suitable for obtaining excellent deep-UV photoresponse. In this work, we have grown high...

description Deep-UV light detection has important application in surveillance and homeland security regions. CH(3)NH(3)PbX(3) (X = Cl, Br, I) materials have outstanding optical absorption and electronic transport properties suitable for obtaining excellent deep-UV photoresponse. In this work, we have grown high-quality CH(3)NH(3)PbX(3) (X = Cl, Br, I) bulk crystals and used them to fabricate photodetectors. We found that they all have high-sensitive and fast-speed response to 255 nm deep-UV light. Their responsivities are 10–10(3) times higher than MgZnO and Ga(2)O(3) detectors, and their response speeds are 10(3) times faster than Ga(2)O(3) and ZnO detectors. These results indicate a new promising route for deep-UV detection.
