On the Ordering of Na$^+$ Ions in Na$_x$CoO$_2$

On the Ordering of Na$^+$ Ions in Na$_x$CoO$_2$

The influence of electrostatic interactions on the ordering of sodium ions in Na$_x$CoO$_2$ is studied theoretically through Monte-Carlo simulations. For large $x$ small di- or tri-vacancy clusters are stable with respect to isolated Na vacancies. At commensurate fillings these small clusters order...
