▎ 摘　　要

Graphene-like thin films were grown on patterned SiO2 substrates by simple thermal chemical vapor deposition using ethanol. The film growth occurred preferentially in the vicinity of pattern edges. Catalytic metal is not necessary for the substrate or the pattern. The films consist of graphitic nanocrystals of several nanometer scale. In the electric properties, the field effect is observed at room temperature. (c) 2010 Elsevier B.V. All rights reserved.
