| Abstract: | This paper presents the definitions and calculation formulas of characteristic features of the O-lattice, including the principal O-lattice vectors, the principal O-lattice planes, and the O-cell walls. A matrix method is provided for calculating the periodic dislocation structures in general interfaces, and a vector method is given for calculating the dislocation structure in special interfaces. The condition and limitation for application of the O-lattice model are discussed. Discussion has also been made considering non-periodic dislocation structure and dislocation structures in interfaces with large lattice misfit. |
