| Abstract: | A study of photoinduced high-Tc superconductivity is presented by canonical two-band BCS model containing Fermi surfaces of p and d holes. We have obtained two superconducting gaps from this model. Studies of chemical potential and hole concentration dependences on critical temperature (Tc) are made. The enhancement of Tc is found due to doping.The study of specific heat and density of states based on this model is also presented. The dependence Tc(nh) for the system YBa2Cu3O7?x (1 2 3) obtained theoretically agrees with the available experimental data. |
