Abstract
Surface reconstructions involving curved graphitic overlayer are proposed to be the missing transition state between the clean (2 × 1)- and fully hydrogenated (1 × 1)-diamond (111) surfaces. First-principles calculations show that surface graphitization causes changes in the H vibration frequency, in good agreement with experiment. Localized graphitization may also introduce voidlike planar defects that increase the surface-to-bulk ratio. We find that phosphorus solubility is significantly enhanced near the surface region. This provides an explanation for the recent experimental success on n-type diamond.
