HREM studies suggest that there are two types of twin boundaries in YBa2Cu307-δ. one with a lattice translation (∼d110) along the boundary for fully oxygenated samples, and the other without a lattice translation for oxygen-deficient ones. Originally, the displacement was attributed to observational phenomena caused by misalignment of the crystal. However, diffraction analysis and twin boundary fringe contrast analysis showed that the lattice translation at the boundary is an intrinsic property of the twin boundary in fully oxygenated YBa2(Cu0.98 M0.02)3O7-δ (M = Cu, Zn, and Ni, and δ∽0.0). To further understand the kinetics of twin boundary formation, we present additional observations on twinning dislocation and structural transition of the twin boundaries.
