"WebIn general, band gaps computed with common exchange-correlation functionals such as the LDA and GGA are severely underestimated. Typically the disagreement is reported to be ~50% in the literature. Some internal testing by the Materials Project supports these statements; typically, we find that band gaps are underestimated by ~40%. " - Mit ab-initio phase stability

Webstable phase. It has not been determined until now whether the 9R structure of fcc metals is metastable. If so, it can be stabilized in epitaxial ﬁlms and at grain boundaries by the same mechanism as the hcp phase. While the energies and stability of various crystalline structures of metals can be calculated by ab initio methods, Webab initio data in the ﬁtting database are successful in predict-ing the structural energy differences between various phases and the instability of the bcc and sc structures.8,20 …
