摘要: In this thesis, an enhancement of ultra-violet (UV) sensing performance of Mn doped ZnO UV sensors was presented. Two different types of sensors were developed, including single nanowires sensor and nanoforest type sensor. Different fabricating processes of ZnO nanowires such as, vapor-liquid-solid method and low temperature aqueous solution method, were compared and discussed to optimize the photoresponse of Mn doped ZnO sensors. The mechanism, that Mn doping influence to the UV photoresponse of ZnO nanowires, was also suggested. Two methods were used to fabricate pure ZnO and Mn doped ZnO nanowires. In first method, ZnO nanowires were grown on Si(100) substrates with gold catalyze by vapor-liquid-solid method and then processed by ion-implantation to dope Mn. In another method, the reacting solution to growth pure ZnO nanowires by low temperature aqueous solution method containing Hexamethylenetetramine (HMTA, C6H12N4) and Zinc acetate (Zn(CH3COO)). For Mn doping, Manganese(II) chloride (MnCl2) was directly adding into the reacting solution. A series of analysis including FESEM (field emission scanning electron microscopy), EDS (energy dispersive spectroscopy), XRD (X-ray diffraction) and TEM (transmission electron microscopy) were performed to analyze the properties of ZnO nanowires. Results suggest a low temperature aqueous solution method is more suitable for fabricating ZnO nanowires UV sensors. Single ZnO or Mn/ZnO nanowire UV sensor was fabricated by focus ion beam deposition. The sensing abilities of ultra-violet sensors were examined under irradiation of 365 nm and 400 nm ultra-violet lights. The sensor with Mn doped ZnO nanowire showed an enhancement on sensing ability than the sensor with pure ZnO nanowire. Other ZnO and Mn/ZnO nanostructures UV sensors were also fabricated by low temperature aqueous solution method. The nanostructures were found to enhance the photoresponse of ZnO films. A possible mechanism, which related to surface sites of nanowires and desorption of gas molecules, was suggested to explain the results. The mechanism suggested that the Mn atoms near to surface of ZnO nanowires can influence UV photoresponse according to model of oxygen and water molecules desorption and re-adsorption. Nanoforest type UV sensors were fabricated in used of three different types of substrate and were grown by low temperature aqueous solution method. Mn doping level were controlled by adjust concentrations of chemicals in reacting solutions. Nanowires growing on different substrates were found have different morphologies. In compare of three kinds of substrates, substrates type II, which have ~180nm ZnO seed layer deposited by sputter, are found most suitable to fabricate nanoforest type UV sensor. The ZnO or Mn doped ZnO nanowires can grow on the substrates type II vertically. A model was suggested that nanowires forest were playing a role of charges' buffer or reservoir. First principle calculations were performed to understand the properties of Mn doped ZnO nanowires. Results of first principle calculations showed that doped Mn atoms were prefer to stay at shell of ZnO nanowires. Band structures of ZnO and Mn doped ZnO nanowires were also simulated.
