Description
Summary:The adiabatic cristal model is offered. It is shown that springy nuclei oscillations relatively electronic envelops and waves of such oscillations (inherent oscillations and waves) may exist in crystals. The analysis of experimental temperature dependencies of resistivity in semiconductors with electron-vibrational centres has shown that inherent oscillations effectively interact with crystalline phonons as well as with electrons and holes, creating powerful interaction of electrons and holes with phonons. The experimental narrow peaks of phonon-drag thermoelectric power at Debye temperatures from 77K to 700K confirm existence of inherent oscillations waves in crystals. Inherent oscillations and waves gives rise to strong electron-phonon interaction and probably can bring about superconductivity at temperatures as below so and well above room temperature.
