Interband transitions in epitaxial ferroelectric films of NaNbO3./sub
Original language description
The interband optical transitions in cube-on-cube-type epitaxial ferroelectric NaNbO3 thin films and a reference antiferroelectric NaNbO3 crystal are studied in the spectral range of 0.74?9 eV using variable-angle spectroscopic ellipsometry. The energiesand the types of the transitions in the films are found to differ significantly from those in the crystal and to vary with epitaxial strain. The results are discussed in terms of epitaxial effects, including higher crystal symmetry, anisotropic latticestrain, and ferroelectric polarization in the NaNbO3 films compared to the crystal.
