Observation of Lattice Defects in Graphite by Electron Microscopy, Part I

概要

論文の詳細を見る
In Part I, lattice defects which can a priori exist in graphite crystals and be observed by means of electron microscopy, mainly dislocations, are reported. Four kinds of dislocations and their combination predicted from the crystal structure are observed through the diffraction contrast and the disturbances in the moire pattern such as the extra terminating half lines and the line shift. Their network arrangements and movement are also found. The line grating model reveals the relation between the line shift of the moire fringes and the Burgers vector of the glissile dislocations. New origins of extra terminating half lines are considered too.
