title: Destruction of the small Fermi surfaces in NaxCoO2 by disorder.
abstract: We show using density functional calculations that the small e'g 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.
