“…Hence, decreased ZnO NP size on the seed leads to smaller diameter ZnO NRs with high aspect ratios as increasing Gamodified layer. Zhang et al found that wider ZnO nanowire (NW) arrays are grown on larger crystal grain sizes of AZO [29]. To confirm this previous observation, we prepared a ZnO seed layer by sputtering.…”

“…The 2Â values of the (0 0 2) peak shifts from 34.48 • to 34.76 • , which corresponds to the 2Â value of ZnO NRs from undoped to Ga-modified seed layer conditions. The shift of the diffraction peak can be associated with the release of tensile strain developed within the seed layer [29]. As the covalent bond length of Ga O is slightly smaller than that of Zn O, and Ga substituted at Zn sites would reduce the lattice constant along the c-axis, a compressive strain is induced in ZnO films, which is responsible for the shift of the (0 0 2) peak.…”

“…To further improve the crystallinity of ZnO NWs, the doped Zn-based seed layers can be used. At present, several kinds of doped Zn-based seed layers have been used to ZnO NWs hydrothermal growth, such as Al-doped ZnO (AZO) [85] and Ga-doped ZnO (GZO) [86] thin films. Muchuweni et al reported the hydrothermal synthesis of ZnO NWs on rf sputtered gallium and aluminium co-doped ZnO (GAZO) thin film as seed layers [87].…”

Ultraviolet photodetectors have attracted significant research attention in recent years due to their potential applications in civilian and military fields. ZnO nanowires and nanorods have been regarded as the most potential candidates for ultraviolet photodetectors fabrication because of their peculiar characteristics and size effect, which are different from their bulk material. Recently, many novel routes and semiconductor features, such as the surface and interface engineering, the pryo-phototronic effect, the piezo-phototronic effect, the surface plasmon effect and the surface functionalization have been utilized to improve the photoelectric characteristics of ultraviolet photodetectors. Thus, the working mechanism of these effects existing in ZnO nanowires/nanorods-based ultraviolet photodetectors should be investigated in-depth. In this paper, firstly, the hydrothermal method and the chemical vapor deposition method, as two typical synthesis methods of ZnO nanowires are briefly reviewed. Secondly, we focus on reviewing the properties of varied ZnO nanowires/nanorods-based ultraviolet photodetectors constructed using the above mentioned semiconductor features with metal-semiconductor-metal structure, Schottky barrier structure, vertical p-n heterojunction structure and core-shell heterostructure. Furthermore, the most attractive self-powered ultraviolet photodetectors are systematically reviewed. For various ZnO nanowires/nanorods-based ultraviolet photodetectors, we put the emphasis on the working mechanism of semiconductor features to improve the properties of the photodetectors. Finally, we give an outlook on the future development of ZnO nanowires/nanorods-based ultraviolet photodetectors.
