GROWTH OF POLYCRYSTALLINE DIAMOND OVER GLASSY-CARBON AND GRAPHITE ELECTRODE MATERIALS

Boron-doped polycrystalline diamond thin films were grown over glassy carbon electrode material and POCO graphite by a microwave plasma-assi sted chemical vapor deposition (CVD) using a gas mixture of methane an d hydrogen. As-deposited films were analyzed by scanning electron micr oscopy (SEM) and Raman spectroscopy for their morphology and chemical nature, respectively the diamond films grown over glassy carbon and gr aphite electrode material may have some use in electroanalysis since t he doped diamond films are electrically conductive, erosion resistant, and chemically inert.
