Summary
The use of EC-STM to study the relationship between surface structure and surface reactivity in situ on electrodes in contact with an electrolyte is of major importance in corrosion research. Highlighting this essential topic in corrosion science, this book supplies the reference material and procedural guidelines required for the application of electrochemical scanning tunnelling microscopy (EC-STM). STM-users are instructed how to obtain high resolution data on a carefully prepared copper single-crystal surface. After reviewing the background of the copper system, the book covers experimental design, moire pattern formation on Cu, and problems with imaging.
