“…Therefore they postulate that solitons are responsible for the asymmetric interfacial scattering process. Later similar thermal rectification effect has been observed in molecular dynamic simulation of mass-graded carbon nanotubes [12][13][14]. In the simulations, the atomic mass of carbon atoms is gradually increased from 12 to 300 along the axis of tubes.…”

“…Theoreticians, on the other hand, have widely used these nanosized systems to check the transferability of physical concepts developed for perfect one-dimensional (1D) chains to experimentally accessible quasi-1D systems. In recent articles, 5,6 we have analyzed the justification of this transfer for the thermal conductivity (k). The k parameters of CNTs have been studied both experimentally [7][8][9][10][11][12] as well as by molecular dynamics (MD) simulations of the nonequilibrium type.…”

“…13,[14][15][16][17][18][19][20][21] The observation of thermal rectification (R t ) in externally mass-loaded carbon and boron nitride nanotubes 22 has lead to a renaissance in the research of the heat transfer in nanotubes. 5,6,13,[23][24][25][26][27][28][29] R t = 0 characterizes a difference in the heat transport in two opposite directions. Reverse nonequilibrium MD (RNEMD) simulations have become a powerful tool to quantify the length (l), diameter (d), and temperature (T) dependence of k in CNTs.…”

“…[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] Because the vibrations inducing the structural deformation have a lower frequency than thermal phonons and propagate ballistically in comparison with them, we need an elastic-wave rectifier [31][32][33][34][35][36] rather than the thermal rectifier in order to achieve the expected performance of the nano-device, NEMS and so on.…”
