abstract = "The structural and electrical properties of Schottky contacts and gold films on remote plasma-cleaned, n-type ZnO{0001} surfaces are discussed. Current-voltage measurements of Au contacts deposited on cleaned, n-type ZnO(0001) surfaces showed reverse bias leakage current densities of ∼0.01 A/cm 2 at 4.6 V reverse bias and ideality factors > 2. The similarly deposited Au Schottky contacts initially grew through the same mechanisms. The Plasma cleaning and cooling both surface in vacuum eliminated all detectable hydrocarbon contaminant, reduced the amount of the hydroxide layer to ∼0.4 ML, and resulted in a 0.7-eV reduction in downward band bending and 0.7 eV lowering of the surface Fermi level.",
