Abstract In this paper, we have modified the Cooper theory by considering a biexcitonic attractive interaction for high T c superconductors. We have developed an expression for (2Δ/K B T c) as a function of phonon and biexciton mediated coupling constants. For the sake of simplicity, we use a two-square-well potential model (electron–phonon and electron–biexciton). The calculated values of (2Δ/K B T c) show good agreement with experimental values.
