Abstract

Yttria-stabilized zirconia and cerium dioxide thin films are deposited in oxygen-deficient environments and compared to those deposited in oxygen-rich environments. Oxygen-deficient films are highly (001)-oriented, which corresponds to a surface that should be forbidden based on Tasker's theoretical calculation. Oxygen-vacancy-induced surface reconstruction and relaxation are proposed to explain the phenomenon. The analysis is consistent with preferred orientations previously observed in indium tin oxide, SnO ₂, and NiO films. Detailed studies of preferred orientations of these oxygen-deficient metal oxide films are of importance for their use in solid oxide fuel cells, gas sensors, and optical devices, etc.
