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

(Nanowerk News) Researchers from the Institute for Nuclear Research and the Baikov Institute of Metallurgy and Material Science, both in Moscow, Russia, are proposing that that nanocomposites of phonon resonant cavities (NPRC) will possess an interesting electrodynamic properties.
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.
