Phonon barrier-electron penetration effect
WebDec 7, 2024 · Any description of an electron attracting "nearby" ions is therefore a simplified picture, because "nearby" is ill-defined. But it is true that electrons interact with the phonons, and that this causes a small attraction between the electrons, which are otherwise repulsed by … WebOct 25, 2014 · That charge buildup keeps the electrons in Cooper pairs from getting too close to each other, despite the attraction created by their phonon-coordinated charge wobble. This repulsion effect keeps the electrons in a Cooper pair surprisingly far from each, in the order of hundreds of atomic diameters apart.
