One of the tools for topographic characterization is Scanning Probe Microscopy (SPM). For the morphological studies of gold substrates with face 111 [Au (111)] and Highly Ordered Pyrolytic Graphite (HOPG) Atomic Force Microscopy (AFM) and Tunneling Effect Microscopy (STM) were used. As a result of the visualization and characterization of the Au (111) substrate we have: gold grains with measurements of 359 nm from AFM and gold terraces with heights of 0.2 nm by STM. In the HOPG substrate we observed by AFM terraces with measurements of 0.359 nm and by STM carbon atoms with interatomic distances of 0.2727 nm... View more»
