Abstract

TDPAD studies of¹⁹F recoil-implanted into (natural) diamond, show not less than three characteristic sites populated by¹⁹F in the diamond lattice. Two are distinctive lattice locations, but the third is identified as having a broadly distributed and randomly oriented electric field gradient, with a quadrupole coupling constant consistent with that of a H-F bond. The fraction of¹⁹F ions in this third configuration shows a systematic dependence on the dose of protons used in the recoil implantation process. The interpretation of this phenomenon is assisted by comparison of data for bulk solid diamond (natural and synthetic), with thin (20 μm thick) diamond, and also concurrent nuclear reaction analysis determination of the bulk hydrogen concentration in the sample. In-beam TDPAD is shown as able to give a dynamic insight into beam induced molecular re-arrangements in the TDPAD time window immediately following recoil implantation.
