PAIRING THEORY OF HIGH-TC AND LOW TC SUPERCONDUCTORS

New solutions for T(c), the order parameter, and the density of states are obtained, based on the fact that pairs are formed within the pairing interaction range, T(D) (Debye), via the BCS pairing theory (not the BCS results). They are valid for all y = T(D)/piT(c), and are applicable to low T(c) (LTS) and high T(c) (HTS) superconductors. The order parameter variation with y is shown to account for all features of HTS. A new density of states via the zero order parameter outside the pairing interaction range is found to account for low energy states observed in HTS. For large y (LTS), the BCS results are reproduced.
