Abstract
We propose an analytic interpolation scheme to include correlation effects in the local-field correction G(q,{omega}) of a two-dimensional electron gas (2DEG). The parametrized form of G(q,{omega}) combines the asymptotic limits for long and short wavelengths, and low and high frequencies, as well as the dynamic nature of the Hartree-Fock approximation. We find that, similar to the 3D case, the correlation contribution to G(q,{omega}) becomes dominant for large q. (author). 14 refs, 2 figs.
