reactivity, chemistry, and termination are important in reproducibly controlling the elec-
trode’s physicochemical properties (McCreery 2008). Several groups have contributed to
the understanding of the factors that inuence the electrochemical response of diamond
materials including those of Swain, Hamers, Carlisle, Garrido, Angus, Butler, Martin,
Fujishima, Nebel, May, Panizza, Comninellis, and Compton.
10.3.1 Cyclic Voltammetry of NCD Films
Cyclic voltammetry (CV) technique is generally useful for examining the diamond lm
quality because the electrochemical response is highly sensitive to physicochemical
properties of the electrode surface. In CV technique, the potential E between the work-
ing elect
