|Issue Date:||Jul-2012||Citation:||Tamang, R., Varghese, B., Tok, E.S., Mhaisalkar, S., Sow, C.H. (2012-07). Sub-bandgap energy photoresponse of individual V 2O 5 nanowires. Nanoscience and Nanotechnology Letters 4 (7) : 716-719. ScholarBank@NUS Repository. https://doi.org/10.1166/nnl.2012.1381||Abstract:||Photoresponse of individual V 2O 5 nanowire (NW) under different controlled conditions were investigated. Individual V 2O 5 NW showed a significant photoresponse at vacuum condition and very small photocurrent (~1 nA) in ambient condition, upon global irradiation of 808 nm laser beam. The photoconducting properties of the V 2O 5 NW are investigated at various pressure conditions and with varying laser power. The observed sub-bandgap energy laser irradiation induced photoresponse can be attributed to factors such as defect level excitation, desorption of adsorbed gas species and laser induced heating effects.
