Abstract
The Schottky barrier height of Pt contacts on n-type thin film ZnO was analyzed which was deposited by pulsed laser deposition. The Schottky barrier height was obtained from current-voltage measurements as function of temperature. Large reverse current magnitude was also observed as compared to that predicted by thermionic emission. The results show rectifying behavior of Pt contacts on ZnO with barrier height at 25°C of 0.61 eV. After annealing this barrier height reduced to 0.42 eV at 300°C.
