High Crystalline Cu₂O Thin Films Prepared by Electric Current Heating Using Copper Wire

Article Preview

Abstract:

Cu wires were heated by electric currents to fabricate Cu₂O thin films. The films were successfully deposited on glass substrates placed above the wires at air pressures in the range of 100 - 40 Pa. Then the films were annealed in a controlled atmosphere and investigated the crystallinity, morphology and the time response to illumination of the films. After annealing at 800 °C at atmospheric pressure with oxygen partial pressure of 12 Pa, the crystallinity was increased and the time response of photoconduction was successfully improved.
