On highly ordered pyrolytic graphite, HOPG(OOOl) electrodes, no UPD has been detected owing to weak carbon-lead interactions [311]. Deposition occurs by three-dimensional island growth according to Volmer-Weber mechanism. Initial steps are controlled by progressive nucleation on active sites and hemispherical diffusion. [Pg.822]

Figure 10.2 Fe(CN) /4 voltammetry on glassy carbon (GC) fractured in solution, and on basal plane highly ordered pyrolytic graphite (HOPG). 1 mM K4Fe(CN)6 in 1 M KC1, scan rate = 0.2 V/s. AEp for fractured GC voltammogram = 64 mV, corresponding to k° > 0.1 cm/s, AEp for HOPG = 1005 mV, k° = 1 x 10 6 cm/s. Potential scale is relative to silver quasi-reference electrode.

In an STM experiment the dendrimer sample deposited on a conductive substrate (e.g. highly ordered pyrolytic graphite (HOPG)) is scanned line-by-line with a fine conductive microscopy tip. Depending upon the measuring mode, a piezoelectric scanner moves either the microscopy tip over the sample surface or the sample under the fixed tip. The microscopy tip approaches the sample... [Pg.271]
