Abstract
Section titled āAbstractāBoron-doped diamond single crystal was synthesised from Fe-Ni-C-B system at 1773 K and 5.6 GPa for 10 minutes. The crystal shape, structure and morphology of boron-doped diamonds were studied using X-ray diffraction, atomic force microscopy and field emission electron microscopy. Results showed that the {111} faces of boron-doped diamond are prevailing. Field emission electron microscopy and atomic force microscopy analysis indicate the terrace-like and zigzag growth steps both present on (100) and (111) facets with the terrace-like steps are dominant on (100) crystal plane, and the height of the steps is in the range from 3.10 to 5.02 nm. The stepās growth is proposed to result from the boron atom incorporation.
