It is shown, that plasmonic metamaterial nanostructures could be used to reduce the electron-phonon scattering rate, by providing an alternative, fast electron-plasmon scattering channel. Since the plasmon-phonon and plasmon-photon scattering processes are relatively slow, this provides a mechanism for a hot-electron plasmonic protection against the phonon emission. The stored/protected energy can be returned to the single particle channel by processes similar to the Rabi oscillations, plasmon resonance energy transfer (PERT), or formation of plasmarons. This effect could be used to control phonon scattering in various electron systems, such as solar cells or high Tc-superconductors.
