Vibronics of multi-material nanopillared membranes and impact on the thermal conductivity
Lina Yang, Mahmoud I. Hussein
Atomic motion in nanopillars standing on the surface of a silicon membrane generates vibrons, which are wavenumber-independent phonons that act as local resonances. These vibrons c…
