“…ZnO has attracted more attention than other transparent conducting oxides because of its large exciton binding energy (60 meV) [3], low resistivity, abundance, and non-toxicity. The optical properties, crystallinity, and the composition of ZnO depend on deposition methods, deposition conditions, and the type of substrate and annealing process [4][5][6][7]. The crystal structures of ZnO cubic zinc blend or hexagonal wurtzite make it a promising material for high-speed ultraviolet photodetectors and optical devices [8][9][10][11].…”

The fabrication of planar Al/ZnO/Si heterojunction photodetectors has received considerable attention. The crystalline quality of ZnO plays an important role in the properties of the fabricated device. In this study, ZnO micro-rods were grown on Si (100) without any catalysts using atmospheric pressure chemical vapor deposition, and were characterized to determine their potential for application in highly photosensitive ZnO/Si photodetectors. The ZnO rods were grown with various diameters and had a wurtzite structure oriented in the (002) plane. The effect of the substrate temperature on the crystalline structure was studied in the range of 450-750°C. The planar structure of the Al/ZnO heterojunction photodetector indicated that the device is highly sensitive to ultraviolet and visible light. The photoresponse of the fabricated Al/ZnO device had a peak at 360 nm. The responsivity of the device reached 0.03 at a bias voltage of 1 V and reached 0.085 at a bias voltage of 5 V. The responsivity increased to 0.121 as the bias voltage increased to 10 V. The quantum efficiency of the device was 11, 32, and 42 % at bias voltages of 1, 5, and 10 V, respectively.

“…p-Cu 2 O/n-ZnO heterojunction can be grown by using a two-step electrodeposition method [5,6]. The quality of films grown by electrodeposition is strongly dependent upon substrate, temperature of electrolyte, pH, bubbling, and concentration of solute [17][18][19][20][21]. Until now, most Cu 2 O thin films have been grown by using mainly galvanostatic method [6,10].…”

Recent progress in the electrochemical deposition of ZnO nanowires: Synthesis approaches and applicationsIn the last decade, nanostructuration is a demanding research topic due to the observation of interesting properties and, in consequence, applications on these nanostructures. This review collects the synthesis and possible applications of ZnO nanowires grown by electrodeposition and electroless methods. Respect to the synthesis of ZnO nanowires, growth mechanism and parameters are analysed depending on the technique used, electrodeposition or electroless. The mechanism growth of the nanowires using templateless and hard-templates is analysed resulting in different architecture of the ZnO nanowires. Moreover, ZnO nanowires and hybrid materials based on ZnO are also considered. Depending on the architecture of ZnO nanowires, the properties and applications are different.This review also studies the properties and applications in which ZnO nanowires can be used and how these applications are different depending on the architecture of the nanostructure. This review gives a complete perspective referent to the synthesis, properties and application of ZnO nanowires grown by electrosynthesis techniques.
