ABSTRACT
Compared to any other gemstone, diamonds probably feature more predominantly in the history and cultural heritage of the human race. Generally, thin films of diamond are produced through a variety of various physical vapor deposition and chemical vapor deposition (CVD) methods, including ion beam deposition, pulsed laser deposition, plasma enhanced CVD, etc. The cost of diamond is such ($1.00/carat) that quality films are now being produced commercially for use as die cutters for nonferrous materials. Y. Namba first attempted to grow diamond phase carbon films using ethanol solution as electrolyte at a temperature less than 70°C on silicon substrates. A number of organic liquids were utilized as electrolytes by different workers for the deposition of diamond-like carbon (DLC) films by electrode position technique. The electrochemistry process for liquid phase electrode position of DLC films is not very simple, but rather complicated. Literature supports that atomic hydrogen effectively etches graphite phase in vapor phase deposition of diamond film.
