Abstract: The full potential linear augmented plane wave(FLAPW) method is used to study geometric and electronic structure of δ-Pu monolayers corresponding to the (100) and (111) surfaces in the generalized-gradient approximation(GGA). The results show that spin-orbit coupling has a stronger effect on the equilibrium structure and there is a significant compression of monolayer compared to the bulk. It should be possible to grow a thin film of δ-Pu on a substrate whose lattice constant is smaller than that of δ-Pu. For the surface atoms, due to the reduced nearest neighbors, the contribution to the bonding from 5f electrons is reduced and 5f electrons appear to be more localized with a stronger degree for (100) surface than (111) surface.
Key words: FLAPW, δ-Pu monolayer, Localization
