Positive and Negative Photoconductivity Conversion Induced by H(2)O Molecule Adsorption in WO(3) Nanowire

Negative photoconductivity effect has been observed in the Au/WO(3) nanowire/Au devices in a high humidity environment, which might be attributed to the accumulation of H(+) ions on the surface of WO(3) nanowire. Under illumination with violet light (445 nm), the photo-excited holes can oxidize the...
