Abstract

The electrochemical characterization of diamond is just beginning. The study reported here deals with the growth by energy-assisted CVD of impurity-doped diamond electrodes (see Figure) sufficiently conductive for electrochemical measurements. The electrochemical activity of the electrodes towards various analytes, their capacitance and flat-band potentials in several electrolytes, and their photocurrent response are discussed.
