Title: Destruction of the Small Fermi Surfaces in Na xCoO 2 by Disorder

Abstract

We show using density functional calculations that the small e0g Fermi surfaces in NaxCoO2 are destroyed by Na disorder. This provides a means to resolve the prediction of these sections in band structure calculations with their nonobservation in angle resolved photoemission experiments.
