Ruey-Chi Wang, Hsin-Ying Lin, Chao-Hung Wang and Chuan-Pu Liu Photosensors: Fabrication of a Large-Area Al-Doped ZnO Nanowire Array Photosensor with Enhanced Photoresponse by Straining (Adv. Funct. Mater. 18/2012) Advanced Functional Materials 22
A large-area flexible nanowire array photosensor is developed by directly growing horizontal Al-doped ZnO nanowire arrays across Au electrodes on a flexible substrate. This is reported by Ruey-Chi Wang, Chuan-Pu Liu, and co-workers on page 3875 and shown in the false-color scanning electron microscopy (SEM) image. Good nanowire quality and the device layout lead to ultrahigh photoresponsivity and sensitivity. Tensile strain further enhances the photoresponsivity.
