Observation of Dislocations in Tellurium by Transmission Electron Microscopy

Abstract
A method of thinning tellurium single crystals by chemical polishing has been developed for the study of dislocations by transmission electron microscopy. The preliminary results concerning the identification of the glide planes and the Burgers vectors of dislocations in this material are described together with some comments on the contrast phenomena resulting from the high elastic anisotropy of tellurium.
