22 Similarly, charge carrier transport by the Holstein hopping model is strongly influenced by the molecular vibration. good thermal contacts to a thermal bath give more contri-bution in thermal transport than the inner walls, and the ratio of axial to radial thermal conductivity may inﬂuence the conversion of thermal conductance to thermal conduc-tivity. In the following, however, we simply estimate the thermal conductivity neglecting the junction thermal con- The efficiency in modern technologies and green energy solutions has boiled down to a thermal engineering problem on the nanoscale.

The heat flux of CNT-sheet was compared to that of copper, and it was found that the CNT-sheet has significantly higher specific heat transfer properties compared to those of copper. As thermal impedance mismatches between adjacent materials and confined geometries (thin films, nanowires) limit thermal transport, device-level thermal design has become necessary. We have developed temperature mapping techniques based on scanning thermal microscopy to measure the self-heating of nanodevices with resolutions in the nanometer regime.

Thermal conductivity largely depends on the ability of the material to transfer phonon without being scattered . Most crystalline polymers are actually semi-crystalline structures , , , in which both crystalline and amorphous regions are present. This chapter focuses on recent progress in the modeling of conductive thermal transport in a variety of systems and materials, from crystalline solids and nanostructures to molecular junctions, composites, and biological systems. Novel emergent technologies in energy harvesting and conversion, microelectronics, phase-change memories, heat-assisted We combine coarse-grained simulations with concepts known from polymer physics and thermal transport to unveil a generic microscopic picture of κ reduction in molecular forests.
