Transport, electrical and microtopography studies of W3Se4 single crystals
We present studies of temperature and pressure dependent transport properties of W3Se4 single crystals. The electrical resistivity and thermo power while increasing temperature show that the material is semimetallic in nature. The exact behaviour of the pressure dependent resistivity can be extracted on the basis of simple metallic conduction. The study of surface microstructure reveals that the growth of W3Se4 was driven by screw dislocation mechanism.
