Abstract:High resistivity ZnO:Cu thin films were fabricated on c-plane sapphire substrate by low pressure metal-organic chemical vapor deposition (MOCVD). The samples were treated in H-2 ambient at high pressure and the thermal stability of the hydrogen-related donor-like defects was studied. Hall-effect measurement results presented that the high resistivity ZnO:Cu samples turn into n-type conductivity after H incorporation. The annealing results indicated that the hydrogenated ZnO:Cu could not recover high resistivity even after annealed at 750 degrees C. It is proposed that some unknown H-related donor-like defects still exist in the film after annealing. (C) 2013 Elsevier B.V. All rights reserved.
