Thermal rectification and interfacial thermal resistance in hybrid pillared-graphene and graphene: a molecular dynamics and continuum approach

Abstract: In this study, we investigate the thermal rectification and thermal resistance in the hybrid pillared-graphene and graphene (PGG) system. This is done through the classical molecular dynamics simulation (MD) and also with a continuum model. At first, the thermal conductivity of both pillared-graphene and graphene is calculated employing MD simulation and Fourier's low. Our results show that the thermal conductivity of the pillared-graphene is much smaller than the graphene by an order of magnitude. Next, by ap… Show more

“…Also, with increasing temperature, the kapitza resistance decreases, and the thermal conductivity increases. Second, growing the temperature increases the phonon-phonon interaction, and the scattering between them, which leads to a decrease in the thermal conductivity [50]. If one of these two factors overcomes the other, it dominates the thermal behavior of the system.…”

“…Moreover, thermal recti cation has also been seen in other systems. In graphene-C 3 N junction [19,20], graphene-C 3 B [21], graphene-pillared [22], radial recti cation [23], telescopic silicon nanowire [24], and so on. Thermal recti cation in ultra-narrow graphene with functionalized edge via NEMD simulation has been investigated.…”

“…12 Heterostructures, which consist of two or more materials, open new ways for combining and altering physical properties for specific purposes. [13][14][15][16][17] The thermal conductivity of C 3 N monolayer with different porosity, which resembles C 2 N, is studied using molecular dynamics, 18 and the thermal conductivity of C 3 N and C 2 N monolayers evaluated 589 W mK À1 and 52 W mK À1 , respectively, by increasing the porosity, the thermal transport behavior can be changed and reduced up to B15 W mK À1 . A DFT study shows the MoS 2 monolayer-graphene heterostructure has a higher power factor up to B2 times than graphene and MoS 2 , due to the change in the electronic structure.…”
