Pressure induced anisotropy of electrical conductivity in polycrystalline molybdenum disulfide (2006)

Abstract Anisotropic specimens of MoS2 are obtained by pressing the microcrystalline powderinto special die. This inelastic compression results in a rearrangement of thedisulfide micro platelets observed by Atomic Force Microscopy and reflected in themacroscopic anisotropy in electrical conductivity in these samples. The conductivitymeasured parallel and perpendicular to the direction of applied pressure exhibitsan anisotropy factor of ∼10 at 1 GPa. This behaviour of the conductivity as a functionof applied pressure is explained as the result of the simultaneous influence of arearrangement of the micro platelets in the solid and the change of the inter-graindistances.
