Superconductivity in Intercalated Molybdenum Disulfide

Abstract

Molybdenum disulfide has been intercalated with sodium and potassium. Both natural crystals of molybdenite and synthetic crystals were used, and measurements made on the intercalated products indicate a superconducting transition temperature of \ensuremath{\sim}1.3\ifmmode^\circ\else\textdegree\fi{}K for sodium and \ensuremath{\sim}4.5\ifmmode^\circ\else\textdegree\fi{}K for potassium.
