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.
