Thermal conduction through a vented support

Thermal fluctuation-induced tunneling conduction through metal nanowire contacts.

The temperature behavior of how electrons propagate through an insulating electronic contact formed at the interface between a submicron Cr/Au electrode and a metallic RuO(2) nanowire (NW) has been studied between 300 and 1 K. The NWs are typically of ∼70 nm in diameter and a few microns long. The submicron electrodes were fabricated by the standard electron-beam lithography technique. By emplo...

Interface effects in thermal conduction through molecular junctions: Numerical simulations.

Thermal conductance in solid-molecule-solid junctions is studied within Langevin-type classical molecular dynamics simulations. The solids attached at the two ends, characterized by phonon bands mismatching the molecular vibrational window, are simulated using colored thermal noises with analytic correlation functions. We find that the dissimilarity in the vibrational spectra of the molecule an...

Heat conduction through a trapped solid: effect of struc- tural changes on thermal conductance

– We study the conduction of heat across a narrow solid strip trapped by an external potential and in contact with its own liquid. It is possible to produce structural changes in the trapped solid by altering the depth of the confining potential. We find, using nonequilibrium molecular dynamics simulations, supported wherever possible by simple analytical calculations, the thermal resistance in...

The Role of Thermal Conduction in Accretion Disks with Outflows

In this work we solve the set of hydrodynamical equations for accretion disks in the spherical coordinates (r,θ,ϕ) to obtain the explicit structure along θ direction. We study a two-dimensional advective accretion disc in the presence of thermal conduction. We find self-similar solutions for an axisymmetric, rotating, steady, viscous-resistive disk. We show that the global structure of an advec...
