abstract = "Electrochemical activity of doped CVD-diamond electrodes was
investigated as a function of boron content connected with the
films surface characteristics and morphology. A textured cloth of
carbon fibers was used as a substrate with a discontinuous
surface. It was treated using 0.25-mum diamond powder by
ultrasound dispersion in hexane. The nucleation and coalescence of
the diamond film around the fibers was evident. Boron-doped
diamond electrodes have been analyzed in the range of acceptor
concentrations of 10(18) and 10(21) cm(-3). Their electrochemical
behavior was studied by cyclic voltammetry measurements in neutral
(KCl, Na2SO4 and NaNO3) and acidic (HCl, H2SO4 and HNO3)
solutions. The anodic and cathodic currents increase with the
doping level and present a maximum when the electrodes reach a
metallic behavior. For comparison, films grown on silicon
substrate in similar conditions were also studied as standard
diamond electrodes. Surface morphology and film quality was
analyzed by scanning electron microscopy (SEM) and Raman
scattering spectroscopy.",
