dc.description.abstractUndoped and Mg- doped zinc oxide (ZnO) nanorods (NRs) have great potential applications in the fields of optoelectronic devices. Therefore, it is very important to realize the controllable growth of these NRs and investigate their properties. In this dissertation, ZnO NRs were grow on ZnO-seeded p-Si and p-GaN substrates using hydrothermal method for use in ultraviolet (UV) photodetectors and light-emitting diodes (LEDs). The effects of the hydrothermal parameters including the heat-treatment temperature of the seed layer and the zinc nitrate and hexamethylenetetramine precursor concentrations on the formation of ZnO NRs on the p-Si substrate were investigated. The optimum preparation conditions for undoped ZnO NRs were then used to grow Mg-doped ZnO NRs on a p-Si substrate under different hydrothermal parameters. A solution of starting materials and magnesium nitrate as a dopant was used. Varying the reaction temperature and dopant concentration favours the formation of NRs with unique characteristics. The surface morphology, crystallinity, and optical properties of the as-prepared films were systematically investigated.en_US
