Description
We have measured the millimeter-wave (100-GHz) surface resistance of high-quality laser-deposited YBa2Cu3O7 films on SrTiO3 and LaAlO3 substrates. Due to finite film thickness, radiation losses are important in the normal state and in the superconducting state near Tc. These effects are calculated, and Rs characteristics of the ohmic losses in the film are extracted from the data. Rs drops rapidly at Tc, and a detailed comparison with calculations that include finite mean-free-path effects suggests a gap that opens more rapidly as T/Tc decreases and attains a larger 2Δ(0)/kBTc ratio than the standard BCS behavior
