Description

The role played by the lone-pair electrons on the superconductivity of chalcogenide glasses is discussed. It is suggested that many specific features of superconductivity in chalcogenide glasses are due to the superconductivity of a system of negative-U centres, rather than to the BCS nature of the phenomenon.
