Study of Electrical Property of Single Crystals of Tungsten Diselenide

Authors(1) :-D. K. Patel

The requirement for inexpensive and highly efficient solar cell requires continuous exploration of new semi-conductors which satisfy the photo-voltaic criteria established by solar cell base materials like Tungsten Diselenide. Single crystals of W0.80Se2 belonging to transition metal dichalcogenides MX2 group are synthesized in the laboratory. Since the crystals are insoluble in water and decompose before melting point temperature, crystals are grown by Direct Vapor Transport (DVT) technique. The electrical transport properties of W0.80Se2 single crystal are studied and resistivity through Van der Pauw method in the high temperature range (313K –388K) is obtained. Employing the Hall effect measurements, Hall coefficient, mobility as well as carrier concentration have been studied. The Van der Pauw technique is also used to evaluate the type, mobility and carrier concentration of W0.80Se2 single crystals.
