Phonon resonant cavities as a promising building blocks of hand-made nanocrystalline matter

Abstract:
The only mode of high-frequency phonon oscillations that can be obtained in metallic devices made with the use of conventional manufactoring processes is that of travelling wave. Under these conditions any perturbation at a point within the crystal lattice will travel with dissipation in all directions from that point and never come back. In a travelling wave mode phonon oscillation fields are random. Hence, the interaction between conduction electrons and the oscillations of the crystal lattice of an electrical conductor has a viscous nature. We propose to replace the travelling wave mode with the standing resonant wave mode for frequencies from 0.1 to 1 THz and higher.
