An electrical probe of the phonon mean-free path spectrum
Ashok T. Ramu, Nicole I. Halaszynski, Jonathan D. Peters +2
Most studies of the mean-free path accumulation function (MFPAF) rely on optical techniques to probe heat transfer at length scales on the order of the phonon mean-free path. In th…

Reduction of the effective thermal conductivity by circulation of the quasi-ballistic heat-flux
Ashok T. Ramu, Carl D. Meinhart, John E. Bowers
For a thermal conductivity that is spatially uniform and independent of temperature, Fourier's law of heat transfer predicts a curl-free heat-flux. In the quasi-ballistic phonon tr…
