  The performance of two modern density-functionals, HSE06 and TB-mBJ, on
predicting electronic structures of metal oxides, chalcogenides and nitrides,
is studied in terms of band gaps, band structure and projected
density-of-states. Contrary to GGA, hybrid functionals and GGA+U, both new
functionals are able to predict band gaps with an appreciable accuracy of 25%
and thus allow the screening of various classes of (mixed) metal oxides at
modest computational cost. The calculated electronic structures are largely
unaffected by the choice of basis functions and software implementation.
