Considerations on growth parameters for dynamic congruent-state growth of linbo₃

Each ionic species of LiNbO₃melt hasa particular field-modified equilibrium partition coefficient, k_E0, and effective partition coefficient, k_E, which are predominated by growth parameters, i.e., solute boundary layer thickness,ै_C, growth velocity, V and temperature gradient, G_L.Variationsofthese coefficients have been discussed in association with growth parameters and a combinationof ै_C(g), V(g)and G_L(g) asa function of solidified melt fraction, was calculated for true dynamic congruent-state growth from a finite amount of melt when the interface electric field is taken into account.
