摘要
SnO2 thin films were grown on Si substrate using the chemical vapor deposition(CVD) method. The surface of the thin film was examined using a transmission electron microscope (TEM) and a scanning electron microscope (SEM). Atypical shaped grains and atypical columnar structures were observed on the SnO2 thin films that were exposed to air after first deposition and during re-deposition in anaerobic conditions in the CVD. The electrical properties of SnO2 thin films feature a lower range of resistance in single mode, but after the atypical particles appear, the electrical resistance decreased. (C) 2013 Elsevier Ltd.
