Structural Features of Nominally Pure Lithium Niobate Crystals Grown from Boron-Doped Charge

Abstract:

The features of the structure of single crystals LiNbO₃:B³⁺ (0.12 and 0.18 wt %) grown by the Czochralski method from the mixture of different genesis were studied. It was found that boron is able to incorporate into the crystal structure of lithium niobate in a trace amounts (~ 10^–4–10^–5 wt %), decreasing the concentration of structural defects Nb_Li. Thus, ordering of structural units of the cation sublattice of lithium niobate crystals grown from a congruent composition melt approach in that of stoichiometric crystals.
