“…A scattering boundary method within the lattice dynamic approach [12,13,14] fully considers the atomic structures in the interface; but it can only be applied to ballistic thermal transport. Classical molecular dynamics is another widely used method in phonon transport [15,16,17], which is not accurate below the Debye temperature, and ignores the quantum effect. Only recently the nonequilibrium Green's function method, which originates from the study of electronic transport [18], been applied to study the quantum phonon transport [19,20,21,22].…”

Abstract. The thermal transport across metal-insulator interface can be characterized by electron-phonon interaction through which an electron lead is coupled to a phonon lead if phonon-phonon coupling at the interface is very weak. We investigate the thermal conductance and rectification flowing between the electron part and the phonon part using nonequilibrium Green's function method. It is found that the thermal conductance has a nonmonotonic behavior as a function of average temperature or the coupling strength between the phonon leads in the metal part and the insulator one. The metal-insulator interface shows evident thermal rectification effect, which can reverse with changing of average temperature or the electron-phonon coupling.PACS numbers: 63.20.kd, 72.10.Di Thermal transport across metal-insulator interface via electron-phonon interaction 2

“…[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.…”

We propose a rectifier of elastic waves in a thin plate, which is made of an elastically isotropic material containing a periodic array of triangular holes as scatterers, and demonstrate numerically that it works both for the symmetric and anti-symmetric Lamb waves as well as shear horizontal waves. The rectification is caused by the geometric effects on wave scattering due to the asymmetric scatterers, while the interplay between the mode conversion and interference effects among the scattered waves owing to the periodic arrangement of scatterers complicates it. The mechanism makes it possible to rectify the typical elastic waves in the system above the threshold frequency corresponding to the wavelength equivalent to the periodicity of scatterers.

“…Recently, it is found that phonons can be also used to carry and process information [8][9][10][11][12][13][14][15][16][17]. More importantly, different thermal (phononic) devices such as thermal rectifier, thermal transistor, thermal logic gate, and thermal memory, have been conceptualized.…”

In this paper, heat flux in graphene nano ribbons has been studied by using molecular dynamics simulations. It is found that the heat flux runs preferentially along the direction of decreasing width, which demonstrates significant thermal rectification effect in the asymmetric graphene ribbons. The dependence of rectification ratio on the vertex angle and the length are also discussed. Compared to the carbon nanotube based onedimensional thermal rectifier, graphene nano ribbons have much higher rectification ratio even in large scale. Our results demonstrate that asymmetric graphene ribbon might be a promising structure for practical thermal (phononics) device.
