Query: Electronic structure of CrN: A comparison between different exchange
  correlation potentials   We report a series of electronic structure calculations for CrN using
different exchange correlation potentials: PBE, LDA+$U$, the Tran-Blaha
modified Becke-Johnson, and hybrid functionals. In every case, our calculations
show that the onset of magnetism in CrN should be accompanied by a gap opening.
The experimentally found antiferromagnetic order always leads to an insulating
behavior. Our results give further evidence that the Tran-Blaha functional is
very useful for treating the electronic structure of correlated semiconductors
allowing a parameter free description of the system. Hybrid functionals are
also well capable of describing the electronic structure of CrN. The analysis
of the system is complemented with our calculations of the thermopower that are
in agreement with the experimental data.
