Analysis of temperature dependent I – V measurements on Pd/ZnO Schottky barrier diodes and the determination of the Richardson constant

Temperature dependent current–voltage ( I – V ) and Hall measurements were performed on Pd/ZnO Schottky barrier diodes in the range 20–300 K. The apparent Richardson constant was found to be 8.60 × 10 - 9 A K - 2 cm - 2 in the 60–160 K temperature range, and mean barrier height of 0.50 eV in the 180...
