Abstract: | The surface conductivity of the polar ZnO faces was changed by exposure to H and O2, by Ar ion bombardment and by heat treatments. Simultaneous studies of the corresponding Electron Energy Loss Spectra in the range 3–20 eV surprisingly indicated that the lowest energy state, at 3 eV, was not involved in these conductivity changes. The only states that could be involved were at 5.3 and 14.3 eV. |
