Abstract
Study by inelastic electron tunneling spectroscopy of 30 Å ZnO layers grown by thermal oxidation of zinc to form Zn/ZnO/Pb and Al/Al2O3/ZnO/Pb tunnel junctions is reported. Second derivative (d2V/dI2) peaks reveal additional transverse optical and longitudinal optical phonons of energy 12.6 meV and 15.4 meV respectively in ZnO. The barrier height at the Zn-ZnO interface is found to be 0.4 eV, consistent with the usual n-type semiconductor picture of ZnO.
