Effect of the Perdew-Wang Generalized-Gradient Correlation Correction. 

Calculated using the frozen-core projector augmented wave mediod based upon the DFT with the Perdew—Wang generalized gradient approximation for F—A. The electron eflfective masses were 0.31... 

The DMoF DFT code provided in Materials Studio 4.0 was used to perform all the electronic structure calculations [21,22]. A norm conserving, spin unrestricted, semicore pseudopotential [23] approach was nsed with electron exchange and correlation accounted for using the Perdew-Wang generalized gradient approximation (GGA) [24].

Unless otherwise stated, all of our calculations used the generalized gradient approximation as defined by the Perdew-Wang 91 functional. In shorthand, we used PW91-GGA calculations. Unless otherwise stated k points were placed in reciprocal space using the Monkhorst-Pack method. Some specific details for the calculations from each section of the chapter are listed below.
