Full Relativistic Electronic Structure and Fermi Surface Sheets of the
First Honeycomb-Lattice Pnictide Superconductor SrPtAs    [PDF]

Saad Elgazzar, A. M. Strydom, Stefan-Ludwig Drechsler

We report full-potential density functional theory (DFT)-based {\it ab initio} band structure calculations to investigate electronic structure properties of the first pnictide superconductor with a honeycomb-lattice structure: SrPtAs. As a result, electronic bands, density of states, Fermi velocities and the topology of the Fermi surface for SrPtAs are obtained. These quantities are discussed in comparison to the first available experimental data. Predictions for future measurements are provided.
