Abstract: Using molecular dynamicsMD simulations, we study thermal transport ingraphene nanoribbons GNR subjected to uniform uniaxial and nonuniform strainfields. We predict significant thermal rectification over 70% in arectangular armchair GNR by applying a transverse force asymmetrically. Theheat flux is larger from the less stressed region to the more stressed region.Furthermore, we develop a theoretical framework based on the non-equilibriumthermodynamics to discuss when thermal rectification under a stress gradientcan occur. We conclude with a discussion of details relevant to experiment.
