Periodic micro- and nanostructures in LiNbO3〈Gd〉 single crystals grown under unsteady-state conditions
Source abstract
Abstract
Gd-doped lithium niobate single crystals having a regular domain structure with a period from 100 to 1 μm have been grown under highly unsteady thermal conditions. Examination by atomic force microscopy shows that such lithium niobate single crystals contain periodic nanostructures with a period from 10 to 100 nm in the region of regular domain structures. Raman scattering data suggest that the cation sublattice of the lithium niobate crystals contains a superstructural sublattice of defect clusters with a step of 1–2 nm. We conclude that lanthanide-doped lithium niobate single crystals contain periodic fractal structures in a range of length scales, from ≃ 1 nm to 100 μm.
