The cold electron emission behaviors of zinc oxide nanowires, nanopins and vertical aligned nanofibres are studied. The factors that influence the electron emission process such as the geometry and the energy level structure of nanostructured zinc oxide are discussed in theory and experiment. Good field emission performances have been obtained from the vertical aligned nanofibre with sharp tips and gallium doping 关键词: band structure;electron field emission;fibres;gallium;II-VI semiconductors;nanowires;semiconductor doping;wide band gap semiconductors;zinc compounds;field emission;one-dimensional nanostructured zinc oxide;cold electron emission;zinc oxide nanowires;nanopins;vertical aligned nanofibres;gallium doping;energy level structure;ZnO:Ga
