The oxidation of CVD diamond films

Assessment of acid and thermal oxidation treatments for removing sp2 bonded carbon from the surface of boron doped diamond

“…Higher temperatures were not investigated to limit damage to the remaining sp 3 material, with rapid graphitisation reported at 700 o C in air. [57] [31] is less thermally stable than that found on the BDD surface after ns-laser machining. This may be due to the presence of the "denatured graphite" layer.…”

Oxidation electronics: bond–band–barrier correlation and its applications

“…Nimmagadda et al [509] suggested that oxidation occurs preferentially at regions of grain boundaries, local defects and diamond-like carbon phase during the earlier stages of oxidation. An investigation by Zhu et al [510] revealed that diamond oxidation occurs at $ 1070 K and suggested that diamond oxidation depends on the crystal orientation and defect density. Thermal-programmed desorption (TPD), EELS and AES investigating the oxidation of single crystal diamond (111) and (110) surfaces [511] revealed that molecular oxygen is easily chemisorbed on the clean diamond surfaces at room temperature.…”

Assessment of Acid and Thermal Oxidation Treatments for Removing Sp2 Bonded Carbon from the Surface of Boron Doped Diamond

“…Higher temperatures were not investigated to limit damage to the remaining sp 3 material, with rapid graphitisation reported at 700 o C in air. [57] carbon coating on a nanodiamond, which consists of carbon onions, graphite ribbons, amorphous carbon and fullerenic shells [31] is less thermally stable than that found on the BDD surface after ns-laser machining. This may be due to the presence of the "denatured graphite" layer.…”
