Abstract

This study reports the deposition of cuprous oxide [Cu ₂O] onto titanium dioxide [TiO ₂] nanowires [NWs] prepared on TiO ₂/glass templates. The average length and average diameter of these thermally oxidized and evaporated TiO ₂ NWs are 0.1 to 0.4 μm and 30 to 100 nm, respectively. The deposited Cu ₂O fills gaps between the TiO ₂ NWs with good step coverage to form nanoshells surrounding the TiO ₂ cores. The p-Cu ₂O/n-TiO ₂ NW heterostructure exhibits a rectifying behavior with a sharp turn-on at approximately 0.9 V. Furthermore, the fabricated p-Cu ₂O-shell/n-TiO ₂-nanowire-core photodiodes exhibit reasonably large photocurrent-to-dark-current contrast ratios and fast responses.
