摘要：

During a LEED examination of the CoO(100) surface a number of extra spots were observed in the LEED pattern. These spots indicated the presence of a faceting of the surface, and appeared upon annealing to 1100 K. Further analysis of the extra spots indicates that the faces of the structures formed are the CoO(110) planes. An STM study of the reconstruction revealed it to consist of pyramidal surface depressions of sizes up to 500 Angstrom by 500 Angstrom. (C) 1998 Elsevier Science B.V.
