Abstract
The continued-fraction expansion algorithm is utilized to clarify the hierarchy among the coincident-site lattice structures. Boundary energ ies are calculated against twist misorientation based on a two-dimensi onal version of the model suggested by du Plessis and van der Merwe in 1965, which reveal a fractal energy surface with cusps at very SIGMA value. The origin of the cusps and the effects of local structural rel axation on the boundary energies are discussed.
