Growth of Antimony on Copper. A Scanning Tunneling Microscopy Study: This study investigates the Copper(111) - Antimony (Sb) system which is characterized by a complex interplay between adsorbate interactions and adsorbate substrate interactions which manifest through self-assembly processes. Surface sensitive techniques such as Low Energy Electron Diffraction and Auger Electron Spectroscopy were utilized to determine the substrate cleanliness prior to the growth of monolayer Sb coverage. The surface chemical reactivity on an atom-by-atom basis of the Cu sample surface was studied by current imaging tunneling spectroscopy. The use of surface sensitive techniques in studying the surface alloy in question allows for more precise statements to be made about the surface structure of the system at various temperatures. Based on the experimental results, a comprehensive study of the adsorption and segregation behavior of Sb on Cu(111), including the mechanisms for phase formation at the atomic scale, is presented in this study.

The surface chemical reactivity on an atom-by-atom basis of This study investigates the Copper(111) ? Antimony (Sb) system which is characterized by a complex interplay between adsorbate interactions and adsorbate substrate interactions which manifest through self-assembly processes. Surface sensitive techniques such as Low Energy Electron Diffraction (LEED) and Auger Electron Spectroscopy (AES) were utilized to determine the substrate cleanliness prior to the growth of monolayer Sb coverage. The surface chemical reactivity on an atom-by-atom basis of the Cu sample surface was studied by current imaging tunneling spectroscopy (CITS). The freely diffusing Sb adatoms on the copper surface were thermally excited from a random distribution of Sb atoms after growth to a finally rearrangement of a more energetically stable configuration. All the superstructures obtained were found to favour a structural model based on Sb atoms occupying substitutional rather than overlayer sites within the top Cu(111) layer. The local density of states (LDOS) were derived from dI/dV maps at low tunneling voltages by a simultaneous measurement of high resolution topographic micrographs. The onset of the atomically clean Cu(111) surface was determined to be ~8 meV below EF which reflects the onset of tunneling from the surface state band as determined by scanning tunneling spectroscopy. The use of surface sensitive techniques (LEED, AES, STM, STS) in studying the surface alloy in question has enabled more precise statements to be made about the surface structure of the system at various temperatures. Based on the experimental results, a comprehensive study of the adsorption and segregation behavior of Sb on Cu(111), including the mechanisms for phase formation at the atomic scale is presented in this study.
