Phonon Resonators : The Building Blocks of Nanocomposite Adjusting the Electron - Phonon Interaction

TL;DR

This paper introduces phonon resonators formed by nanocrystallites with discrete oscillation modes, which can be amplified to create nanocomposites with tunable electronic properties and potential high-temperature superconductivity mechanisms.

Contribution

It proposes a novel approach to create phonon resonators using nanocrystallites with discrete modes, enabling adjustable material properties and new mechanisms for high-temperature superconductivity.

Findings

Discrete phonon modes in nanocrystals can be amplified via resonant standing waves.

Nanocomposites of phonon resonators can be engineered for tunable electronic properties.

A new mechanism for high-temperature superconductivity based on phonon resonators is suggested.

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 resonators whose oscillation modes will represent the standing waves and, will be amplified by the resonant manner. The composites made of phonon resonators will allow to produce a perspective functional material for the electronics with adjustable structure and properties. Some new mechanism of HTS based on phonon resonators is proposed.
