Abstract
In this thesis, the growth of ZnO nanorods and the application of ZnO nanorods such as UV detector has been studied. ZnO nanorods were grown by simple vapor-phase-transfortation (VPT) method and structural, optical and electrical characterization were performed. The feasibility of nanorods to an application for UV detector is investigated.

In the chapter 1, a brief introduction of nanomaterial and nanotechnology, growth process of ZnO nanostructures and the fundamental ZnO properties are described. The chapter 2 explains the principals of scanning electron microscopy (SEM), transmission electron microscopy (TEM), photoluminescence (PL) and high resolution x-ray diffraction (HRXRD). In the chapter 3, the growth conditions are investigated and the feasibility of AuGe as a novel catalyst is examined. ZnO nanostructures were grown by simple vapor phase transportation method in a function of growth temperature. In the chapter 4, the growth mechanism is studied through the ZnO nanorods grown on ITO glass. The growth rate of ZnO nanorods were controlled by growth parameters such as growth temperature and carrier gas flow. In the chapter 5, ZnO nanorod device by using sandwiched Si-substrates was investigated. Various metals were pre-deposited on the Si-substrates and ZnO nanorods were grown on it. Electrical characterization and photocurrent properties were investigated by using a Shottky contact ZnO nanorods. In the chapter 6, the obtained results from this thesis are summarized and concluded.
