Synthesis and characterization of indium intercalation compounds of tungsten disulphide: InxWS2 (0 ⩽ x ⩽ 1)

The present work reports on the synthesis of indium intercalation compounds In_xWS₂ (0 ? x ? 1). The material has been characterized by X-ray studies for structure determination and particle size distribution, room temperature magnetic susceptibility, thermoelectric power experiments and conductivity measurements in the temperature range 150–300 K. These results have indicated that, like the host material WS₂, the intercalated compounds also possess hexagonal symmetry and are diamagnetic p-type semiconductors. The activation energy for these compounds was determined from the conductivity data.
