Production of B-Doped Diamond Films for use as Inert Electrochemical Electrodes
We have worked on the production of boron-doped CVD diamond films for use as inert electrodes in electrochemical applications, e.g. cyclic voltammetry. Boron doping is achieved using B2H6 gas at concentrations of a few 100 ppm in the usual CH4/H2 gas mixture. Diamond films can be made with conductivity ranging from highly insulating, through various degrees of semiconductivity, to fully metallic, depending upon the B-doping level we choose. Electrochemistry experiments using these films, and with films of nanodiamond, are performed in David Fermin's group.
