Electronic and Lattice Dynamical Properties of the Iron-Based Superconductors LiFeAs and NaFeAs
The electronic structure and lattice vibrational frequencies of the newly discovered superconductors, LiFeAs and NaFeAs, are calculated within density functional theory. We show that, in the vicinity of the Fermi energy, the density of states is dominated by contributions from Fe 3d states. We also...
