Towards room-temperature superconductivity

By taking advantage of a stability criterion established recently, the critical temperature T-c is reckoned with help of the microscopic parameters, characterising the normal and superconducting electrons, namely the independent-electron band structure and a repulsive two-electron force. The emphasis is laid on the sharp T-c dependence upon electron concentration and inter-electron coupling, which might offer a practical route toward higher T-c values and help to understand why high-T-c compounds exhibit such remarkable properties.
