Positive and Negative Photoconductivity Conversion Induced by H2O Molecule Adsorption in WO3 NanowireDOI: 10.1186/s11671-019-2978-y Keywords: Hexagonal WO3 nanowire, Negative photoconductivity, Positive photoconductivity, Hydrogen ion, Schottky emission Abstract: Typical I-T curves (Vds？=？3？V) of an Au/h-WO3 NW/Au device recorded repeatedly with laser (445？nm, 500？mW) on and off under 40%RH (a), 50% RH (b), 60% RH (c), and 70% RH (d). The lower inset of a: SEM image of an Au/h-WO3 NW/Au device, the nanowire between two electrodes with a diameter of about 300？nm, and a length of about 4？μ
