Optimised ZnO nanorod characteristics are essential for novel devices to operate efficiently, especially shifting the n-type nature towards intrinsic or p-type. The effects of argon bombardment for varying amounts of time on the surface chemistry and Fermi level of ZnO nanorods have been studied using XPS. Bombardment at 5 keV removed surface contamination caused by amorphous carbon and OH−, H2O and C-O groups. The bombardment also causes the O1s, Zn2p and valence band to shift to lower binding energies, indicating a shift towards intrinsic behaviour. Bombardment time can be used to effect a shift of up to 0.8 eV, and this shift remains after the nanorods were re-contaminated by exposure to ambient conditions for 28 days. These results indicate that argon bombardment can permanently shift the n-type nature of ZnO to intrinsic for use in novel devices.
