Resonant cavities can amplify phonon modes for functional materials

Abstract

The nanocrystallite have the finite number of the oscillation modes. Their number increases proportionally to a cube of the characteristic size. Thus the oscillation spectrum of nanocrystal becomes discrete, and the separate modes of oscillations does not interact with each other, that considerably strengthens all phonon modulated processes in a crystal. Covering of such a nanocrystallite with the shielding surface of a material with the higher nuclear weight will allow to create the phonon resonant cavity whose oscillation modes will represent the standing waves and, will be amplified by the resonant manner. The composites made of phonon resonant cavities will allow to produce a perspective functional material for the electronics with adjustable structure and properties.
