Band gaps in pseudopotential self-consistent GW calculations
V. A. Popa, G. Brocks, P. J. Kelly
For materials which are incorrectly predicted by density functional theory to be metallic, an iterative procedure must be adopted in order to perform GW calculations. In this paper…

The difference between Si and Ge(001) surfaces in the initial stages of growth
G. Brocks, J. H. Snoeijer, P. J. Kelly +2
The initial stages of growth of Ge and Si on the Ge(001) surface are studied and compared to growth on the Si(001) surface. Metastable rows of diluted ad-dimers exist on both surfa…
