The temperature dependence of field emission properties of silicon carbide (SiC) nanowires was studied in a range from 27°C to 300°C by using transparent anode technique. The SiC nanowires of diameter of around 15 nm were grown on silicon carbide substrate by thermal heating using iron as catalyst. The results show that above a threshold temperature, the field emission current increases significantly...
A simple and cheap way to fabricate large area ZnO nanoemitter cold cathode was introduced. The properties of the cold cathode were characterized. The potential application of the cold cathode in flat panel light source was also discussed.
The standard Fowler-Nordheim theory has been widely used and achieved great success in description of field emission (FE) experiments for over 70 years. In this paper, we present the field emission models for carbon nanotubes, wide-band-gap nanowires, and metallic nanosheets, emphasizing the deviations against the Fowler-Nordheim theory and some aspects that have not been incorporated in the standard...
This paper investigates the field emission phenomenon of various nanowires and nanorods. The materials of particular interest include Mo and W and their oxides, SiC and ZnO. Different novel techniques are developed for large-area nanowire synthesis like thermal evaporation, thermal heating and by solid-gas interaction at room temperature
