Destruction of the small Fermi surfaces in Na $_{x}$ CoO $_{2}$ by Na disorder

arXiv:cond-mat/0604002 · doi:10.1103/PhysRevLett.97.016404

Abstract

We show using density functional calculations that the small $e_{g}^{'}$ Fermi surfaces in Na $_{x}$ CoO $_{2}$ are destroyed by Na disorder. This provides a means to resolve the prediction of these sections in band structure calculations with their non-observation in angle resolved photoemission experiments.
