Investigations Of The Morphology Of Copper Surfaces By Scanning-Tunneling-Microscopy
Résumé
The main results of Scanning Tunneling Microscopy (STM) studies of the morphology of copper surfaces are presented. It illustrates the ability of this technique to investigate the relationship between surface morphology and the atomic mechanisms which determine it. The first study concerns the equilibrium fluctuations of steps on surfaces vicinal from (100), the second the vacancy and adatom islands generated by low energy ion bombardment on the (100) face of copper.
