Abstract

Lithium cobaltate (LiCoO₂) films were prepared on the (001), (110), (11̄0) and (11̄2) planes of Al₂O₃ single crystals substrates by metal organic chemical vapor deposition, and the phases, orientated textures and surface morphologies were examined. (001)-oriented LiCoO₂ films were obtained on (001) and (110) Al₂O ₃ substrates, while (018)- and (104)-oriented LiCoO₂ films were grown on (11̄0) and (11̄2) Al₂O₃ substrate. Triangular and elongated rectangular faceted structures were directionally aligned, and (001)- and (018)-oriented grains were epitaxially grown on (001) and (11̄0) Al₂O₃ substrates. Randomly arranged polygonal faceted structures were observed in the (001)-oriented LiCoO₂ film on (110) Al₂O₃ substrate, while locally inhomogeneous grains were observed in the (104)-oriented LiCoO2 film on (11̄2) Al₂O₃ substrate.
