p-Cu(2)O-shell/n-TiO(2)-nanowire-core heterostucture photodiodes

This study reports the deposition of cuprous oxide [Cu(2)O] 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...

description This study reports the deposition of cuprous oxide [Cu(2)O] 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(2)O fills gaps between the TiO(2 )NWs with good step coverage to form nanoshells surrounding the TiO(2 )cores. The p-Cu(2)O/n-TiO(2 )NW heterostructure exhibits a rectifying behavior with a sharp turn-on at approximately 0.9 V. Furthermore, the fabricated p-Cu(2)O-shell/n-TiO(2)-nanowire-core photodiodes exhibit reasonably large photocurrent-to-dark-current contrast ratios and fast responses.
