BCS THEORY -- BCS THEORY OF SUPERCONDUCTIVITY
BCS
Theory is based on interaction of two electrons through the interaction
of two electrons through the intermediary of photons. When an electron
approaches an ion in the lattice, there is a coulomb attraction between
the electron and the lattice ion. This produces a lattice distortion
which causes increases in the density of ions in the region of
distortion. The higher density of ions in the distorted region attracts
another electron. Thus a free electron extorts attractive force on
another electron through phonons which are quanta of lattice vibration.
