Abstract
Surfaces (001) of alkali halide crystals (KCl, NaCl), which were obtained by cleavage in air and ultrahigh vacuum, have been studied by Auger electron spectroscopy. It is established that the surface obtained by cleavage in ultrahigh vacuum has an anomalously high conductivity, which is broken down during heating and depositing an atomic layer of metal (Au).
