Abstract
Ternary germanide Sr (AlGe) is a superconductor at 6.7K. We report the results of an ab initio study of electronic, and detailed lattice dynamical properties of superconducting material. The calculations have been carried out within the local density functional approximation using norm-conserving pseudopotentials and a plane-wave basis. The vibrational properties and the electron–phonon calculations are represented using density functional perturbation theory.
