Marks Density functional theory in the LDA+ U approximation is used to calculate the electronic structure of germanium δ doped with phosphorus and arsenic. We characterize the principal band minima of the two-dimensional electron gas created by δ doping and their dependence on the dopant concentration. Pop... [Phys. Rev.
