The [V 6O12] clusters are not stable units in the gas phase but form spontaneously on a metal surface. On the surface the oxide building blocks can be organized into different 2D oxide structures by adjustment of the oxygen chemical potential. 关键词: Thermodynamics;Self assembly;Nanostructured materials;Scanning tunneling microscopy;Structural analysis;Self assembly process;Nanoscale oxide;Chemical potential
