Energy Gap in Superconducting Fullerides: Optical and Tunneling Studies.

Tunneling and optical transmission studies have been performed on superconducting samples of Rb3C60. At temperatures much below the superconducting transition temperature Tc, the energy gap is 2D ­ 5.2 6 0.2 meV, corresponding to 2DykBTc ­ 4.2. The low temperature density of states and the temperature dependence of the optical conductivity resemble BCS behavior, although there is an enhanced “n...

Energy Gap Reduction in Superconducting Tin Films by Quasiparticle Injection

In Sn-I-Sn-I-Pb tunneling structures the energy gap ~Sn of Sn is reduced by quasiparticle injection via single-particle tunneling between the Sn films. ~Sn as function of the quasiparticle density is probed by the Pb contact and found in agreement with the theory of OWen and Scalapino. An instability of the energy gap of Sn is observed at the critical gap reduction ratio predicted by this theor...
