Query: Contribution of the acoustic waves to near-field heat transfer   Calculations of the radiative and phonon heat transfer between metals in an
extreme near field in presence of electrostatic potential difference are given.
Potential difference leads to a coupling between the radiation field and
acoustic waves in solid, as a result of which the heat flux between two gold
plates associated with p -polarized electromagnetic waves increases by many
orders of magnitude as the potential difference varies from 0 to 10V. The
radiative heat transfer is compared with the phonon heat transfer associated
with the electrostatic and van der Waals interactions between the surface
displacements. For large potential difference and small distances the radiative
heat transfer is reduced to the electrostatic phonon heat transfer. A
particular case of surface acoustic waves - Rayleigh waves is studied in
details. Conditions are obtained for the existence of surface phonon polaritons
associated with the interaction of Rayleigh waves with an electromagnetic
field. The surface Rayleigh and bulk acoustic waves can give contributions of
the same order. The obtained results can be used to control heat fluxes at the
nanoscale using the potential difference and to create coherent radiation
sources based on the properties of the Rayleigh waves
