Illustration of Cooper pair
formation
An electron moving from left to right causes an enhancement of positive charge density
between the ions of the lattice, giving rise to a longitudinal compressional wave moving
through the lattice. The quanta of this acoustic wave are called "phonons". The enhancement
of positive charge density attracts another electron. The attraction is strongest if the
second electron happens to move in opposite direction to the first one.
The attractive force between the two electrons, mediated by the positive
ionic charge density enhancement ("electron-phonon interaction") is larger than the
repulsive Coulomb force between the electrons and causes a transient weakly bound
pair ("Cooper pair").
