Abstract

The remarkably fast Na⁺ transport along certain planes in single-crystla Naβ-alumina was reflected in an unusual response to electron-bombardment during AES experiments. When a crystal face perpendicular to these "conduction planes" was bombarded, a concomitant, relatively low, negative surface-charging forced out large quantities of the mobile sodium ions. The migrating ions were reduced at the Naβ-alumina surface to give, after some bombardment time, a thick metallic overlayer which showed a characteristic Auger spectrum with several plasmon loss peaks ∼5 eV apart. The short-term variations in the sodium Auger line intensity allowed quantitative characterization of the Na⁺ fast diffusion along the conduction planes to the surface.
