摘要：

Scanning tunneling microscopy investigations on nucleation and growth of the (2×1)O-Cu(110) structure revealed that the new phase is formed by condensation of mobile chemisorbed O atoms with Cu adatoms evaporating from steps and diffusing across the terraces of the substrate surface. This process can be regarded as two-dimensional precipitation from a dilute mixed fluid into a solid phase rather than a solid-solid transformation. The resulting structure is more appropriately described to be of added-row rather than of missing-row type. © 1990 The American Physical Society.
