In this chapter, the principles of atomic force microscopy (AFM) and mainly of scanning tunneling microscopy (STM) are described. For applications in electrochemistry, in situ operation and the potentialities of STM and AFM are addressed.
STM, a powerful technique for obtaining local structure information of model electrodes on an atomic level and in real space, is highlighted by several case studies, relevant to fuel cell systems: (i) preparation and characterization of well-ordered noble metal surfaces; (ii) noble metal deposition on foreign substrates; and (iii) nanostructuring of surfaces by the STM tip.
