摘要: Highly rectifying Ag, Au, Pd, and Pt Schottky contacts have been fabricated on heteroepitaxial pulsed-laser deposited ZnO-thin films by reactive sputtering. X-ray photoelectron spectroscopy revealed an oxidation of the contact material; gold are purely metallic. The necessity a conductive capping oxidized is proven photocurrent measurements AgxO contacts. ideality factors effective barrier heights were determined current-voltage measurements. Capacitance-voltage temperature dependent furthermore carried out to determine mean height, standard deviation respective voltage dependencies taking lateral fluctuations height into account.
