Abstract
We have investigated experimentally the effect of lateral
confinement of acoustic phonons in ridges as a function
of the temperature. Electrical methods are used to
generate phonons in 100nm large nanostructures and to
probe the nanostructure temperature in the same time,
what allows tracking the heat flux generated and its
possible deviation from Fourier diffusive heat
conduction. We compare our results with those of a recent
theoretical paper based on the ballistic-diffusive
equations.
