| Popis: |
We performed point-contact and tunneling measurements on the organic superconductors beta-(BEDT-TTF)2I3 and beta-(BEDT-TTF)2IAuI, in the normal and superconducting states. The point-contact measurement in the normal state provides the Eliashberg function alpha2(omega)F (omega). This function has maxima at 4 and 15 mV, as well as a sharp peak at 1 mV which seems to indicate a very soft phonon strongly coupled to the electrons. The measurements in the superconducting state provide the superconducting gap, which for the tunneling measurements has a value 2Delta/kB Tc=4, just slightly above the BCS value. |
