Abstract

Auger analysis made along the conduction planes of sodium β″-alumina crystals shows an increase with time of the Na-signal intensity. Scanning microscopy analysis reveals the growth of sodium metallic clusters on the surface at the impact point of the primary electron beam. Results obtained bombarding the surface parallel to the crystallographic c-axis direction show that the sodium concentration either remains stable or decreases, depending on the electron fluxes.
