| Research Abstract |
Less is known about relationship between surface termination of diamond and its mechanical properties, although it is essential to clarify wear resistances of diamond surfaces in various circumstances. In this study, hydrogen, oxygen and nitrogen terminations were prepared by plasma treatment, annealing in air, and ion irradiation, respectively. Confocal Raman spectroscopy with high accuracy was developed to clarify the lattice deformation on the surface of the terminated diamonds. We observed a down shift of bulk phonon of diamond as large as 0.3 cm-1, suggesting effects of surface termination on mechanical properties of the surface.
