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 pair ing interaction range, T(D) (Debye), via the BCS pairing theory (not t he BCS results). They are valid for all y = T(D)/piT(c), and are appli cable 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 HT S. A new density of states via the zero order parameter outside the pa iring interaction range is found to account for low energy states obse rved in HTS. For large y (LTS), the BCS results are reproduced.
