Typical FESEM morphology of an oxygen ion implanted UNCD film.
Uv Raman spectra of three O+-implanted UNCD films: O14 (1 × 1014 cm−2 dose, 1000 °C annealing), O15 (1 × 1015 cm−2 dose, 1000 °C annealing), and O16 (1 × 1016 cm−2 dose, 900 °C annealing). The inset is the ID/IG values and the FWHM of G peaks as a function of oxygen ion dose.
(Color online) The plain view morphologies from HRTEM of O14 samples series annealed at (a) 500 °C, (b) 900 °C and (c) 1000 °C with scale bar of 5 nm, the graphs of sample annealed at (d) 500 °C and (e) 900 °C with scale bar of 2 nm, and the morphologies of STEM of O14 sample annealed at (f) 500 °C and (g) 900 °C.
Uv Raman spectra obtained from a series of O14 samples after annealing at 500, 650, 800, 900, and 1000 °C, respectively, for 30 min.
Dependences of (a) the values of IDia/Isum and ID/IG and (b) the FWHM values of diamond and G peaks on annealing temperature (T a ).
