Abstract

During the last few years the scanning tunneling microscope (STM) has become an important tool for the investigation of the electrochemical interface, and has been established as one of the few methods that can give atomic resolution. But though the STM has been successfully applied to a number of systems, as is evident from this volume, its mode of operation in electrolyte solutions is not completely understood. For example, it is not clear why certain structures are clearly seen, while others are not. Also, the effective barrier height for the tunneling electron has remained an enigma, with different groups reporting widely different values under similar conditions. Other problems involve the effect of the STM tip on the electrostatic potential in its vicinity, and its influence on reactions such as metal deposition.
