Abstract

In this study, the thermoelectric properties of system based on molybdenum disulfide and tungsten di-telluride are investigated in three combinations with two identical nanoribbons of molybdenum disulfide and tungsten di-telluride in the upper and lower layer, as well as a structure with two different layer, one molybdenum disulfide and the other tungsten-di-telluride. These properties include the electrical conductivity coefficient (G), thermal conductivity (κe), Seebeck coefficient or thermoelectric power (S) and efficiency coefficient (ZTe). which are suitable for the design of thermoelectric devices. The effect of the type of combinations of two-dimensional heterogeneous structures and temperature on thermodynamic properties was investigated. The results show that molybdenum-disulfide/tungsten-di-telluride configuration with Armchair edge structure has the most desirable thermoelectric properties. The results of this article can be useful in the design of nano electric devices based on two-dimensional layers.
