Abstract
The electrical properties of Cr/Pt/Au and Ni/Au ohmic contacts with unintentionally doped In2O3 (U-In2O3) film and zinc-doped In2O3 (In2O3:Zn) prepared by reactive magnetron sputtering deposition are described. The lowest specific contact resistance of Cr/Pt/Au and Ni/Au is 2.94 Ã 10â6 and 1.49 Ã 10â2 Ω-cm2, respectively, as determined by the transmission line model (TLM) after heat treatment at 300 °C by thermal annealing for 10 min in nitrogen ambient. The indium oxide diodes have an ideality factor of 1.1 and a soft breakdown voltage of 5 V. The reverse leakage current prior to breakdown is around 10â5 A.
