Stability of ZnO Polar Surfaces
ab initio calculations have been performed to investigate
the stability of the (0001) and (000-1) surfaces of ZnO. One possible
stabilisation mechanism is the transfer of charge between the two
surfaces leading to a metallisation of the Zn surface and holes
in the 2p band on the oxygen surface.
