Growth, structural and high pressure studies on MoS2 single crystal

MoS2 is a member of transition metal dichalcogenides (TMDC) group. Single crystals of molybdenum. disulphide (MoS2) have been grown by a chemical vapour transport technique using iodine as transporting agent. The composition of the grown crystals was confirmed on the basis of energy dispersive analysis by X-ray (EDAX) and remaining structural characterization was accomplished by X-ray diffraction (XRD) studies. Lattice parameters, volume and X-ray density have been determined for the grown crystals. The particle size for number of reflections has been calculated using Scheffer's formula. The stacking fault probabilities were found for the grown crystals. The behaviour of resistance under pressure is thoroughly studied using Bridgman anvils. The variation of resistance with pressure has been carried out upto 6.5 GPa.
