Abstract

The electronic structure of ZnO nanorods was studied to differentiate local electronic structures at the tips and sidewalls. The overall intensity of the O K-edge x ray absorption near edge structure (XANES) spectra was found to be greatly enhanced for small proton incident angles. Substantial enhancements of O 2p derived states was also shown by both valence band photoemission and O Kedge XANES near the valence band maximum and conduction band minimum respectively. The analysis showed suggested that the tip surfaces of the highly aligned ZnO nanorods were terminated by O ions.
