Mechanism of graphitization and optical degradation of CVD diamond films by rapid heating treatment

Polycrystalline CVD free-standing diamond films have been heat treated through a rapid heating process using a direct current (DC) arc plasma jet system within the temperature range of 1500–2000°C. The optical transmission of the diamond film decreases when the treatment temperature exceeds 1500°C....
