“…The effect of phonon transport and electron-phonon coupling that determine the heat transport at the solid-solid interface has been a long standing problem in condensed matter science both experimentally and theoretically 28 In order to understand the thermal boundary conductance playing an important role in heat transport between materials, we employ the Fourier’s heat transfer model to describe the thermal transport process across the metal-to-semiconductor interface where the metallic film is initially excited by a femtosecond laser pulse and heated via lattice thermalization 29 . In this case, the thermal diffusion equation can be given as where and are volumetric heat capacities of film and substrate, and and are thermal conductivities of film and substrate, respectively.…”

Scattering of energetic charge carriers and their coupling to lattice vibrations (phonons) in dielectric materials and semiconductors are crucial processes that determine the functional limits of optoelectronics, photovoltaics, and photocatalysts. The strength of these energy exchanges is often described by the electron-phonon coupling coefficient, which is difficult to measure due to the microscopic time- and length-scales involved. In the present study, we propose an alternate means to quantify the coupling parameter along with thermal boundary resistance and electron conductivity by performing a high angular-resolution time-resolved X-ray diffraction measurement of propagating lattice deformation following laser excitation of a nanoscale, polycrystalline metal film on a semiconductor substrate. Our data present direct experimental evidence for identifying the ballistic and diffusive transport components occurring at the interface, where only the latter participates in thermal diffusion. This approach provides a robust measurement that can be applied to investigate microscopic energy transport in various solid-state materials.

In the past two decades, with the rapid progress in synthesis of nanoscale materials and manufacturing of low-dimensional structures, it has created a great demand for understanding of thermal transport in nanoscale. The study of heat conduction in nanoscale is beneficial to many applications such as thermal management, thermal protection, thermoelectrics as well as phonon informatics. Here, we provide the reader with insight and an eye-opening review of the impact of atomic coating on the thermal conduction in low-dimensional structures, specially in coherent phonon regime. Typical systems including semiconducting nanowires, carbon nanotubes, two-dimension materials and nanoscale thin film have been considered. This review aims to summarize recent advances with theoretical, experimental and simulative studies toward understanding of thermal conductivity of nano materials with atomic coating. We also report the importance of the top-layer coating on the interfacial thermal conductance in twodimensional devices.

“…The mechanisms can be concluded as follows: systematically the van der Waals interaction at the interfaces [18] , the surface imperfection [19] and phonon scattering [20] , and the phonon attenuation due to the phonon scatterings [21][22][23] . The main factors that govern the interfacial heat transport across the solid-liquid interface are the bonding strength [24] , temperatures [25][26][27] , and surface size [28][29][30] .…”

The mechanism of thermal resistance between graphene layers and nanofluids is essentially important to the performance and reliability of the graphene microchannels. In this paper, the interfacial thermal resistance of the graphenewater, graphene-ethanol, and graphene-ethylene glycol systems are systematically investigated using non-equilibrium molecular dynamics simulations (NEMD). The results showed that the interfacial thermal resistance of the three structures showed different trends as the temperature increased. The interfacial thermal resistance of the graphene-water, the graphene-ethanol, and the graphene-glycol system achieve a minimum value at 285 K, 165 K, and 335 K, respectively. The effects of graphene width on graphene-water interfacial thermal resistance are greater than that of graphene-ethanol and graphene-ethylene glycol systems, however, the thickness of the liquid cluster has greater effect on the interfacial thermal resistance for the graphene-ethanol and graphene-ethylene glycol interfaces than that of graphene-water system. The near-wall density analysis and phonon density of states analysis are calculated to explain the validity of our NEMD simulation results. Our study is helpful for improving the efficiency of the graphene microchannels.
