Abstract

Strong electron-phonon scattering results in a smearing of the peak structure in the electronic density of states in high- $T_{c}$ $A 15$ materials. This smearing may impose limits on the highest $T_{c}$ achievable for these and similar materials. Numerical estimates are made using band structure and electrical resistivity data.
