The DFT calculations were carried out within the framework of the mixed basis pseudopotential method using the local density approximation. A density functional perturbation approach was used for calculating properties of the lattice dynamics and electron-phonon coupling. Details can be found in R Heid and K-P Bohnen, Phys. Rev. B60, R3709 (1999) (10.1103/PhysRevB.60.R3709) / Phys. Rev. by R. Heid (1999)

For the Gaussian smearing used in our calculations, a smearing by 1 meV corresponds approximately to a temperature of 5.5 K
The calculations required about three months of computer time for each value of the smearing parameter, using a very fast work station. Reducing the smearing parameter to 10 meV would require usage of a much denser mesh in q-space and hence an order of magnitude longer computer time

We note that many calculations published in the literature were done with δE = 200 meV, i.e. the largest value used in our study
A better approximation was recently proposed by M Calandra and F Mauri, Phys. Rev. B71, 064501 (2005), which needs, however, a very large computational effort
