Indium intercalation compounds of molybdenum disulphide; In xMoS 2 (0⩽ × ⩽1)

Abstract

The present work reports a detailed investigation on crytal structure, electrical properties, and thermal stability for indium intercalation compounds of molybdenum disulphide. In xMoS 2 (0⩽x⩽1). X-ray analyses show that intercalated compounds, like the host material 2HMoS 2, also possess hexagonal symmetry with a small but continuous increase in interlayer spacing; there also exists a particle size anisotropy. Room temperature thermoelectric power experiments and low temperature (150 – 300 K) conductivity measurements indicate that intercalated compounds also exhibit n-type semiconducting behaviour similar to that of the base material MoS 2. Thermal stability behaviour of these compounds in air and argon atmosphere has also been studied.
