摘要：

Scanning tunneling microscopy (STM) and low energy electron diffraction (LEED) have been used to investigate the oxygen reconstruction following oxidation of a Mo(112) single crystal. The STM and LEED results show a p(1 x 2)-O oxygen-induced missing row reconstruction at monolayer coverage. LEED and high resolution STM data also reveal a second oxygen-induced p(1 x 3)-O reconstruction at a higher oxygen coverage. This latter structure is a precursor to the formation of an epitaxial MoO2(100) surface. (C) 2002 Elsevier Science B.V. All rights reserved.
