摘要:
AbstractThe diffusion‐induced inhomogeneity in the supersaturation on close packed faces of KDP crystals, growing from aqueous solutions has been investigated. The interferometrically found values of the concentration difference on the crystal edge and in the centre of the most closely packed face {100} were compared with the theoretically expected concentration nonhomogeneities calculated by means of CHERNOV's formula. The comparison has been performed especially for the moment when the KDP crystals lose the stability of their polyhedral shape and gradually acquire a skeletal form. A fairly good coincidence was foun

摘要:
AbstractStarting with a quasichemical treatment, simple model calculations are given for the equilibrium composition in surface steps containing A and B kinks, the amount and ratio of which is varied by changing the adjacent gas composition. In connection with deviations from step stoichiometry, the total amount of kinks increases strongly.A nearest neighbour approximation has been applied to the attachment of A or B atoms at kinks from the gas phase, and also from the bulk by formation of vacancies VAor VB. These processes can be formulated separately for the two elements, taking into account the effective formation of bulk atoms of the other kind (BBor BA).

摘要:
AbstractConcentrations of atoms with different numbers of nearest neighbours, and of the kink and non‐kink positions between atoms in step fronts, have been calculated by two treatments. The results differ in the general case, but agree in cases with extreme nonstoichiometry as well as in nearly stoichiometric cases. With respect to the relevance of the model calculations, further investigations are necessary on step reconstructions, on the positions of stability limits of AB compounds in terms of step nonstoichiometry, and on the possibility of roughening transitions in connection with step nonstoichiometry.With increasing nonstoichiometry in the steps, neighbouring kink positions, and the corresponding neighbour‐kink atoms become increasingly important. In contrast to this, the concentrations of double kink positions become smaller, and they vanish in the extreme cases where the PBC‐directed steps consist merely of A, or of B neighbour‐kink atoms. These concentrations are negligible in the extended model calculations at sufficiently low temperatures, together with concentrations of triple and further multiple kink po
