Thermoelectric Effect on Linear Array of Graphene-Based Materials Including Fullerene, Twisted Graphene, and Graphene Nanoribbon

Nowadays, graphene-based materials (GBM) have received huge attention from nanotechnology researchers, mainly owing to their potential applications in thermoelectricity. In the presented work a new approach to the geometrical effects of low dimensional GBM including fullerene, twisted graphene (TWG), and graphene nanoribbon (GNR) on thermoelectric properties are investigated. A liner array of GBM is considered and the transmission possibility of each array under quantum tunneling effect in each region is calculated. Additionally, the geometrical effects of the proposed array including the number of twists, fullerene diameters, and the number of dimer lines on the Seebeck coefficient and energy conversion efficiency (ZT) are discussed. Results clearly illustrate that the effect of twists number is dominant in comparison with fullerene diameter and number of dimer lines variation. Finally, a comparison study is performed, and the achieved results bring new hopes for utilizing the fullerene-TWG-GNR linear array in thermoelectricity.
