△ [11p-M113-13] Formation of Nitrogen-Terminated (111) Diamond with High Nitrogen Coverage
Keywords:Nitrogen-Termination, (111) Diamond, NV Center
Nitrogen terminated (100) diamond with a high nitrogen coverage has been prepared so far that the charge state of shallow NV - in diamond is stable. Nitrogen terminated (111) diamond is presumed to stabilize the charge state of shallow NV -, since the electron affinity on the surface is as positive (+ 3.23 eV) as that of nitrogen terminated (100) diamond. We succeeded in fabricating nitrogen terminated (111) diamond with high nitrogen coverage by using pure nitrogen gas as a radical source for nitrogen beam exposure.
