Resistivity and electron-phonon coupling in YNi${}_2$B${}_2$C single crystals

In this work, we present the results of precise measurements of the resistivity of YNi${}_2$B${}_2$C single crystals with $T_{\mathrm{c}}$ = 15.5 K as a function of the temperature, and analyze the experimental data in the framework of the Bloch-Gr"{u}neisen theory and electron-phonon coupling. The transport electron-phonon spectral function that best fits the resistivity data is then inserted in the real-axis Eliashberg equations, which are directly solved to determine the normalized tunneling conductance both in s- and d-wave symmetry.
