Abstract A new type of k space pairing interaction is proposed, which is induced by the electron(hole)-lattice coupling and which exists in crystals with elementary cells composed of several atoms as, for example in the high-T c systems. The interaction leads to an attractive coupling between charge carriers of arbitrary k vectors. For systems characterized by quasi-two-dimensional motion of charge carriers with small Fermi wave-vectors the superconducting transition temperature T c turns out… CONTINUE READING
