... conductivity ballistic transport heat transport Since the properties of nanosystems depend on temperature, it is logical to study their thermal properties, as for instance, thermal conductivity. In order to do that, one has to note that the classical Fourier law of diffusive regime is no longer...

...F. X. Alvarez; D. Jou We analyze the effects of boundary conditions on the evolution of ballistic heat transport in four theoretical models and propose that a Fourier equation with an effective size-dependent thermal conductivity is a good candidate for the description of ballistic transport when...

... length, varying from about 10 W∕m to 375 W∕m K depending on the various simulation conditions. Phonon decay times on the order of hundreds of fs are computed. These times increase linearly with length, indicating ballistic transport in the nanotubes. A simple estimate of speed of sound, which does...

...-equilibrium phonon distribution function and compare predictions from this model with data for ballistic transport in silicon. The solution to the steady-state transport equations for bulk silicon transistors shows that energy stagnation at the hotspot results in an excess equivalent temperature rise of about...
