S. Jagannathan et al., DIRECT OBSERVATION OF ROUGH-SMOOTH TWIN STRUCTURE IN SILVER-HALIDES BY HIGH-RESOLUTION ELECTRON-MICROSCOPY, Physical review. B, Condensed matter, 53(1), 1996, pp. 9-11
Cross sections of silver halide platelets have been examined by low- a
nd high-resolution transmission electron microscopy. They provide dire
ct, microstructural evidence for the presence of {111}/{001}'/{111} ro
ugh-smooth twin structures in ionic solids.
