摘要：

Surface resistances, R-s, of epitaxial and polycrystalline NbCN films in submillimeter wave region were evaluated from measurements of Fiske-resonant modes in Josephson tunnel junctions. It is found that epitaxial NbCN films have about one order of magnitude smaller R-s values than those for polycrystalline NbCN films. It is also found that the frequency dependence of R-s of epitaxial and polycrystalline NbCN films can be explained by the two-fluid model.
