Abstract

An ultraviolet photosensor has been successfully constructed by the in situ lift-out method in a focused ion beam system. The prototype consists of individual naturally self-assembled crossed ZnO nanorods grown by an aqueous solution process. The current-voltage (I-V) characteristics show linear behavior. The photosensor exhibits a response of similar to 15 mA/W for UV light (361 nm) under 1V bias. Response measurements showed that such a photosensor is suitable for low levels of ultraviolet detection. The method is simple, rapid and applicable to research prototypes for further studies of crossed ZnO nanorods for nano-device applications. (C) 2009 Elsevier B.V. All rights reserved.
