Kurzfassung englisch:
The morphologies of chemical vapour deposited (CVD) diamond films can be changed over a wide range by controlling the process parameters of the deposition. The surface morphologies of the film in turns, govern the micro- and nanomechanical properties of the film. In view of these, diamond films having three different types of morphologies namely coarse ballas, fine ballas and faceted, have been deposited using micro wave chemical vapour deposition (MWCVD) technique. The morphology, and nature of bonds of these films are characterised with the help of scanning electron microscopy (SEM) and Raman spectroscopy. Hardness of the films are evaluated using nano indenter. Force spectroscopy, topographies and lateral force values of these films are estimated by means of atomic force microscopy (AFM). Results indicate that films having fine ballas morphology exhibits the minimum roughness whereas film with faceted morphology has highest relative hardness. The friction force was found to be minimum with the film having fine ballas morphology and the friction force was maximum with film having course ballas morphology.
