Electrical Properties of the MoTe2−WTe2 and MoSe2−WSe2 Systems

Abstract

Electrical resistivity and Seebeck coefficient values were measured on compact polycrystalline samples from the MoSe2−WSe2 and MoTe2−WTe2 systems. In the telluride system the resistivity versus temperature data indicated a number of activation energies from room temperature to the dissociation temperature. In the selenide system there was little divergence from the semiconducting properties of the isomorphic binary compounds. Only one activation energy was found for each of the samples from this system.
