摘要：

We report the effect of silver addition on the surface quality of rf-sputtered Y-Ba-Cu-O thin films. The Y-Ba-Cu-O-Ag films appear to have very smooth surfaces even if the post-annealing step is employed. The surface roughness of our ex situ grown Y-Ba-Cu-O-Ag film, having a 10.3 wt. % of silver, is within ±1% of the film thickness, which is more than 10 times better than the value of a typical post-annealed high-temperature superconducting film without silver.
