Electron locking in layered structures

Research output: Contribution to journalArticlepeer-review


We describe a novel state of electrons and phonons arising in layered structures, like cuprates (HTSC) and semiconductor superlattices (SSL) due to electron-phonon interactions (which can be strongly enhanced by a strong magnetic field). These states are characterized by a localization of phonons and a self-trapping[1-5] or locking of electrons in one or several quantum wells (layers) due to an additional, deformational and/or polarizational potential arising around these locking wells (layers). Using the tight-binding and adiabatic approximations the energy spectrum of such self-trapped states is found.
