Abstract

Scanning tunneling microscopy (STM) and low energy electron diffraction (LEED) have been used to investigate the oxygen reconstruction following oxidation of a Mo(1 1 2) single crystal. The STM and LEED results show a p(1 × 2)-O oxygen-induced missing row reconstruction at monolayer coverage. LEED and high resolution STM data also reveal a second oxygen-induced p(1 × 3)-O reconstruction at a higher oxygen coverage. This latter structure is a precursor to the formation of an epitaxial MoO2(1 0 0) surface.
