Interlayer Induced the Enhancement of Photoresponse Performance for ZnO Nanorods/CuS Heterojunction

Interface enhanced photodetectors based on n-ZnO nanorods/p-CuS heterojunctions are prepared by hydrothermal method with an insulated MgO insert layer. Through our investigation, with the help of the MgO film inserted between the interface of the ZnO NRs and CuS, the device shows a higher photodetectivity and a faster photoresponse speed. For the n-ZnO… (More)
