Title: Quasiparticle self-consistent G W band structure of CrN

Journal Article · · Physical Review B

The band structures of CrN are calculated using the quasiparticle self-consistent GW approach in both the low-temperature antiferromagnetic (AFM) [110]2 Pmna orthorhombic phase and in a hypothetical ferromagnetic phase representing the paramagnetic cubic state in a saturating magnetic field. A gap of about 1 eV is found in the AFM state, while the ferromagnetic band structure is found to be half metallic. Another hypothetical AFM-1 structure [001]1 is further considered and gives a smaller band gap. The orbital nature of the bands is studied and reveals a gap between Cr-d states, indicating a strongly correlated behavior. Here, optical dielectric functions are calculated from the interband transitions and compared to experimental data.
