Abstract :
In this study, the barrier height values of Au/n-ZnO nanowire Schottky diode were obtained from the temperature dependent I-V measurements. The calculated barrier height of Schottky contacts to n-ZnO nanowire using the thermionic field emission model is in good agreement with the value obtained from X-ray photoelectron spectroscopy (XPS) measurements.
