Physical properties of CuCrO2 films prepared by pulsed laser deposition

High-quality CuCrO2 films were prepared by pulsed laser deposition (PLD). The film deposited with the pulse energy density (PED) of 2 mJ/cm(2) is highly c-axis oriented. The refractive index of the CuCrO2 films is about 1.29 obtained by transmission spectra of the films, which implies that the CuCrO2 film will be a potential antireflection coating in visible light. The films prepared with different PEDs show different conduction mechanism, which suggested the different band structure between these CuCrO2 films. (C) 2009 Elsevier Ltd. All rights reserved.
