Abstract

We study the influence of electron-electron interactions on the density of states (DOS) of a clean two-dimensional electron gas. We find that the linear cusp in the DOS around the Fermi level, which was obtained previously, has an additional logarithmic factor. The cusp crosses over to a pure logarithmic dependence further away from the Fermi surface.
