NiO Nanofibers as a Candidate for a Nanophotocathode

Abstract

<i>p</i>-type NiO nanofibers have been synthesized from a simple electrospinning and sintering procedure. For the first time, <i>p</i>-type nanofibers have been electrospun onto a conductive fluorine doped tin oxide (FTO) surface. The properties of the NiO nanofibers have been directly compared to that of bulk NiO nanopowder. We have observed a <i>p</i>-type photocurrent for a NiO photocathode fabricated on an FTO substrate.
