“Background Vanadium pentoxide (V2O5) is the most stable crystallization form and is also the most applicable

in the industry among vanadium oxide systems such as VO, VO2, and V2O3. The orthorhombic layered structure of V2O5 promises a high ionic storage capacity for energy storage applications [1]. Recently, its quasi-one-dimensional nanostructures such as nanowires (NWs), nanobelts (NBs), and nanotubes have gained substantial attention. Due to high surface-to-volume ratio and high surface activity, V2O5 1D structures for various applications, such as field emitters [2–5], transistors [6, 7], chemical sensors [8–10], and lithium batteries [11–14], have been developed. In addition, V2O5 with a direct optical bandgap at visible-light region (E g = 2.2 to 2.7 eV) [2, 15–18] Carnitine palmitoyltransferase II also inspires the studies of optoelectronic applications

such as photodetection [2, 19], optical waveguide [20], and high-speed photoelectric switch [21]. Although device performance of the individual NW has been demonstrated in several studies, fundamental photoconduction (PC) properties and their corresponding surface effects were less studied than the known hopping transport [6, 21–24]. The potential difference of the transport properties of nanomaterials grown by different approaches was also less known. In this paper, we report the study of photoconductivities of V2O5 NWs grown by physical vapor deposition (PVD). The performance of the single-NW device and intrinsic PC efficiency of the material have been defined and discussed. The results are also compared with the reported data of the V2O5 counterpart synthesized by hydrothermal approach.
