Abstract

In this work, using the Tight-binding approximation and kinetic coefficient matrix, the electrical and Thermoelectric properties of four different configurations of single/Bilayer graphene junctions with armchair and zigzag edges are studied. These electrical transport properties include the electrical conductivity coefficients (G), thermal conductivity (􀟢 􀯘 ), thermoelectric power (S) and figure of merit (ZTe), which are suitable for designing thermoelectric devices. The numerical results show that the system can exhibit a metallic or semiconductive behavior with a special edge under different geometric conditions. This makes it possible to exhibit that the thermoelectric power and thermoelectric performance of a relatively large size under particular conditions. In addition, the role of carriers (electron or hole) is clearly demonstrated in terms of electrical and Thermoelectric properties. The results may be useful in designing nanoelectronic devices based on two-dimensional layers.
