The recently growing research field called “Nanophononics” deals with the investigation and control of vibrations in solids at the nanoscale. Phonon engineering leads to a controlled modification of phonon dispersion, phonon interactions, and transport.1,2 However, engineering and probing phonons and phonon transport at the nanoscale is a non-trivial problem.
In this talk, we discuss how phononic properties can be engineered in nanowires 3 and the challenges and progresses in the measurement of the thermal conductivity of nanostructures and low dimensional systems.4
