Far-infrared electrodynamics of superconducting Nb: comparison of theory and experiment
arXiv:cond-mat/0311600 · doi:10.1016/j.ssc.2003.11.017
Abstract
Complex conductivity spectra of superconducting Nb are calculated from the first principles in the frequency region around the energy gap and compared to the experimental results. The row experimental data obtained on thin films can be precisely described by these calculations.
