- •
Films with highly c-axis orientation and optical transparency (60–80%).
- •
Three electronic transitions were uniquely assigned.
- •
The direct transitions are the dominant effect for CuCrO2 optical properties.
- •
Infrared active modes (Eu↑ and A2u↑) can be inferred.
- •
The film density and Hall mobility decrease with increasing annealing temperature.
