Abstract

Natural and synthetic cuprite, Cu2O, have been examined to investigate the radiation stability of the two samples and to find methods of specimen preparation suitable for convergent beam electron diffraction analysis. In this investigation the mineralogical form, stable in the electron beam at room temperature, is found to contain copper-deficient 110 fault planes which would contribute to its three-dimensional rigidity. The defect-free form, obtained by high-temperature annealing, or, as a synthetic crystal, is by comparison radiation sensitive and can only be examined by electrons at liquid nitrogen temperature.
