The screened exchange (sX) hybrid functional can give good band structures for simple sp bonded semiconductors and insulators, charge transfer insulators, Mott–Hubbard insulators, two dimensional systems and defect systems. This is particularly attri... Read More about The effects of screening length in the non-local screened-exchange functional.

Density functional theory in the solid state (2014)
Journal Article
Hasnip, P. J., Refson, K., Probert, M. I., Yates, J. R., Clark, S. J., & Pickard, C. J. (2014). Density functional theory in the solid state. Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 372(2011), Article 20130270. https://doi.org/10.1098/rsta.2013.0270

Density functional theory (DFT) has been used in many fields of the physical sciences, but none so successfully as in the solid state. From its origins in condensed matter physics, it has expanded into materials science, high-pressure physics and min... Read More about Density functional theory in the solid state.

Calculation of metallic and insulating phases of V2O3 by hybrid density functionals (2014)
Journal Article

The electronic structure of vanadium sesquioxide V2O3 in its different phases has been calculated using the screened exchange hybrid density functional. The hybrid functional accurately reproduces the experimental electronic properties of all three p...
