| Abstract: | Lithium niobate single crystals doped with lanthanides (Gd, Er) and nominally pure single crystals of congruent and stoichiometric
compositions have been grown under time-dependent thermal conditions. Regular growth domain microstructures and periodic nanostructures
have been investigated by optical microscopy and atomic force microscopy with a step from 10 to 100 nm. Comparative investigations
of the Raman spectra of lithium niobate single crystals of different compositions have been performed. |
