Defect-related photoresponse and polarization-sensitive photodetection of single ZnO nanowires

Defect-related photoconductivity of single ZnO nanowires is investigated. The photoconductivity shows power-law dependence with incident green laser intensity due to the defect mechanisms including both recombination centres and traps. The device based on single ZnO nanowire shows a sensitive photoresponse to green light with significant on/off ratios. In addition, the photocurrent is highly sensitive to the polarization of the incident illumination. Therefore, the nanowire may act as a polarized photodetector.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000257326000079&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, MultidisciplinarySCI(E)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)4ARTICLE72622-26242
