- Abstract
- We have combined colloidal templating and pulsed laser deposition (PLD) to fabricate arrays of ordered two-dimensional hollow ZnO-NiO mixed oxides. The underlying principle involved in producing colloidal templates by a spin-coating method has been investigated with the use of radial distribution functions. To deposit mixed oxide in a facile manner, we have designed and fabricated a novel PLD target, which has an alternating sequence of pie-shaped ZnO and NiO pieces. Structural characterizations reveal a surface morphology of protruding nano-crystallites, which consist of w체rtzite ZnO and rock salt NiO. The electrical properties have been discussed from the viewpoint of junction effects. Copyright © 2011 American Scientific Publishers. All rights reserved.
