Nanowires on a Film for Photoelectrochemical Water Splitting

Abstract

Nanowires-on-a-film structure (NFS) consisting of a dense array of semiconductor nano‐ wires on a conductive film has recently attracted much interest due to their wide range of applications in electronic, optoelectronic, electromechanic and electrochemical devices [15, 5, 25]. Thanks to their 3D geometry, NFSs provide various morphology-induced advantages resulting in improved devices performances. In addition, as the array of semiconductor NFSs can be grown on a conductive film, which realizes electrical connection between the nanowires, the integration of this nanostructured layer into devices is greatly facilitated.
