Scanning tunneling microscopy (STM) and scanning electron microscopy (SEM) of electrodispersed gold electrodes [PDF]
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1988 Abstract Images of large active surface (electrodispersed) gold electrodes obtained by electroreduction of an oxide layer grown by applying a fast periodic square wave potential to polycrystalline specimens, have been obtained by STM and SEM. For the first time a correlation of imaging data of both microscopes can be established which allows one to ...
