Fabrication and characterization of n-ZnO nanorods/p+-TiO2 heterojunction devices |
초록 |
Trivalent/bivalent metal ions doped p+-TiO2 were prepared wet-chemically and the solution was deposited on indium tin oxide (ITO) coated glass substrates by spin coating method. Vertically aligned n-ZnO nanorods were grown on p+-TiO2/ITO/glass substrates by a seed layer assisted growth technique. Current(I)-voltage(V) characteristics for the Ag/n-ZnO nanorod/p+-TiO2/ITO assembly showed rectifying behaviour with relatively small turn-on (V0) voltages. The effect of thickness and morphologies of n-ZnO and the composition ofp+-TiO2 thin films on the electrical properties were studied. X-ray photoelectron spectroscopy (XPS) confirmed Ti4+ oxidation state of the Ti2p band in the doped p+-TiO2. |
