Abstract

Monolayer guanine on graphite has been studied in NaCl solution by scanning tunneling microscopy (STM) and atomic force microscopy (AFM) as a function of the substrate potential. The STM image of the monolayer changes dramatically as the potential varies, while the AFM image shows no changes over a broad potential range. The observation indicates that the electronic states of organic films can be modified and controlled at solid-liquid interfaces, and STM can provide a local measurement of potential dependent electronic states.
