Fig. 1: Histogram of el-ph coupling properties.
From: The maximum Tc of conventional superconductors at ambient pressure
Histogram of (top) the maxima (\({\omega }_{\max }\)) and logarithmic average (\({\omega }_{\log }\)) of phonon frequencies and (bottom) the electron-phonon coupling constants (λ) calculated for around 20,000 metals (see ref. 43 for computational details).
