Layered metal chalcogenides Superconductivity

Layered chalcogenides such as TaS2 can accommodate large molecules such as stearamide. We shall be discussing the intercalation chemistry of these and other layered materials in Chapter 8. TaS2 is metallic and superconducting [T = 0.8 K) and the superconducting transition is increased to 3.5 K by incorporation of pyridine the interlayer separation increases from 3 to 6 A. Octadecylamine increases the interlayer...
