Extraction of the Eliashberg electron-phonon interaction function from tunneling data. The method and the program
A. I. D'yachenko
Abstract
Mathematical correct method for extraction of the complex superconducting energy gap parameter and electron- phonon interaction function from the tunnel density of states is presented. The computer program is shown to be robust against imperfections in experimental data and is widely used to investigate conventional (low Tc) as well as high- temperature superconductors.
