Abstract

We have investigated experimentally the effect of confinement of thermal acoustic phonons in 100 nm large ridges of silicon and quartz. We quantify the deviation to Fourier and ballistic predictions as a function of two characteristic numbers, the constriction Knudsen number describing the transmission of the phonons and a dimensionless number based on the nanoridges volume/surface ratio.
