Abstract

As diamond becomes more prevalent for electronic and research applications, methods of patterning diamond will be required. One such method, laser ablation, has been investigated in a related work.1 We report on the formation of surface non-diamond carbon during laser ablation of both polycrystalline and single-crystal synthetic diamonds. Near edge x-ray absorption fine structure (NEXAFS) was used to confirm that the non‐diamond carbon layer formed during the ablation was amorphous, and infrared absorption spectroscopy (FTIR) was used to estimate the thickness of this layer to be ~60nm. Ozone cleaning was used to remove the non‐diamond carbon layer.
