The high increase in interface density has become the main bottleneck for heat dissipation gallium nitride/aluminum nitride (AlN)/silicon carbide (SiC) based nanodevices. In this paper, interfacial thermal conductance (ITC) of AlN/SiC is investigated by non-equilibrium molecular dynamics simulation. It found that introducing amorphous layers at will result an enhancement its ITC 2.32 times. Three different are and can be achieved fast annealing. Among them, SiC work best, AlN worst. Further...
Coherent phonons can give rise to phenomena and physical mechanisms in different systems. Understanding phonon-boundary scattering is critical for the manipulation of thermal properties. In this paper, it found that conductivity rough graphene nanoribbon first monotonically changes, then exhibits an oscillatory manner with varying surface boundary roughness. An obvious increase conductivity, up 25.33%, be observed as roughness increases from 0.61 0.72. This contrast conventional...
Utilizing surface roughness to manipulate thermal transport has aided important developments in thermoelectrics and heat dissipation microelectronics. In this paper, through a multiparticle Lorentz gas model, it is found that conductivity oscillates with the increase of roughness, oscillating gradually disappears nonlinearity. The transmittance analyses reveal caused by localized particles due boundary effects. Nonlinearity will break localization. Thus, localization still exists weak...
