Heteroepitaxial (0 0 1) diamond films are successfully grown on high-quality (0 0 1)Ir/(0 0 1)MgO substrates. To enhance the epitaxial nucleation and growth of the diamond, antenna-edge microwave plasma chemical vapor deposition (MPCVD) has been used as a bias enhanced nucleation step. Subsequently, the diamond growth step is performed using conventional MPCVD in a 〈001〉 fast growth mode. Scanning electron microscope (SEM) observation and reflection high-energy electron diffraction (RHEED) reveals the epitaxial ordering of deposited film in several millimeters square area.
