Electron Diffraction Study of the Structures of Antimony Electrodeposited on Antimony Cleavage Face

摘要

Thin layers of antimony of average thickness about one hundred angstroms, electrodeposited at 90°C and 2 ma/cm2 on the (111) cleavage face (referred to pseudo‐cubic axes) of an antimony single crystal, yield abnormal electron diffraction patterns. Analysis of these patterns shows that the deposit crystals are arranged in three azimuthal equivalent orientations, with their (111¯) instead of the (111) lattice planes parallel to the (111) antimony substrate. This is confirmed by comparing the patterns obtained experimentally with those constructed from the Laue zones of reinforcement of the electron beam scattered from three nonparallel atom rows. This observation is discussed in connection with the various factors controlling the crystal orientation in electrodeposited metals.
