Abstract

Thin films of c-axis-oriented LiCoO2were epitaxially grown by pulsed laser deposition (PLD). The ablation laser conditions greatlyaffect the crystal quality of the epitaxial LiCoO2thin films. In addition, high-quality LiCoO2thin films were found to grow without any impurity phases under relatively low oxygen partial pressure,although high pressure had been often selected to suppress the formation of Co3O4 with a lower valence state as an impurity.This result clearly indicates that the ablation laser conditions are an essential growth parameter, and that composition control is indispensable to grow high-quality complex compound thin films by PLD.
