The authors report on the fabrication of transparent rectifying contacts by reactive sputtering of silver or platinum on heteroepitaxially grown zinc oxide. The contacts exhibit Schottky-like current–voltage behavior; the effective barrier height is \(0.73\,\hbox{eV}\) for both materials. In photovoltaic mode, the transparent rectifying contacts reach external quantum efficiencies as high as 32% and responsivities as high as \(0.1\,\hbox{A/W}\).
