| Abstract: | High-quality CuCrO2 films were prepared by pulsed laser deposition (PLD). The film deposited with the pulse energy density (PED) of 2 mJ/cm2 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. |
