초록
Well ordered monolayer arrays of hollow SnO2 shell were fabricated by combining colloidal templating and pulsed laser deposition methods. With increasing the thickness of SnO2 hollow films, their half-spherical morphologies gradually develop to a bell-shaped one. While the surface of SnO2 thin films is fairly flat, the surface of hollow SnO2 shells consists of protruding crystals, indicating morphological dependency on the presence of substrate. Because of the low population of contiguous hollow SnO2 shells, arrays of hollow SnO2 showed higher dc electrical resistance than those of thin films. © 2008 Elsevier B.V. All rights reserved.
