开放的槽行Mo（112）表面作为MoO2外延生长的衬底。在氧暴露的早期阶段，氧的化学吸附诱导Mo（112）表面的缺失行类型的p（2 × 3）表面重构。利用低能电子衍射和扫描隧道显微镜对这种重构表面的表面结构进行了详细的研究。实验结果可以用过渡金属表面氧吸附的有效介质理论解释，为氧修饰的Mo（112）表面提供了结构模型。该结构模型允许讨论氧化学吸附表面相作为在Mo（112）上外延生长MoO2的可能的前体状态。
The open trough-and-row Mo(112) surface serves as substrate for the epitaxial growth of MoO 2 . In the early stage of oxygen exposure, oxygen chemisorption induces a p(2 X 3) surface reconstruction of the missing row type on Mo(112). The surface structure of this reconstructed surface has been studied in detail by low-energy electron diffraction and scanning tunneling microscope. The experimental findings can be explained based on the effective medium theory for oxygen adsorption on transition-metal surfaces, providing a structure model for the oxygen-modified Mo(112) surface. The structure model allows the discussion of the oxygen-chemisorbed surface phase as a possible precursor state for the epitaxial MoO 2 growth on Mo(112).
