· Phys. Rev. B: Condens. Matter; (United States)
Point-contact tunneling into the high-T/sub c/ superconductor La/sub 1.85/Sr/sub 0.15/CuO/sub 4-//sub y/ reveals the first direct measure of the energy gap. Values range from 8 to 14 meV with the variation perhaps due to impurity phases, pressure-induced changes, or anisotropy. Even the minimum value indicates a strong-coupling superconductor.
