FIG. 1.

(Color online) (a) Raman spectra measured on pristine 6H- (blue dashed), Au implanted (1 × 1017 Au ions/cm2) 6H- (blue line), pristine 6H- (red dashed) and Si implanted (5 × 1017 Si ions/cm2) 6H-SiC (red line) after annealing to 1200 °C at 1 × 10−6 Torr pressure. (b) Raman spectra of Au implanted (blue) and Si implanted 6H-SiC (red) after subtracting the pristine SiC background. (c) The D peak Raman shift and D to G peak ratio measured using lasers at different wavelengths.

(Color online) (a) Auger electron spectra taken from 50 to 2200 eV on pristine 6H-SiC (blue) and Au implanted 6H-SiC (red) after annealing to 1200 °C. (b) Detailed Auger carbon peaks measured on pristine (blue), Au implanted (red) 6H-SiC after annealing to 1200 °C, HOPG (black), and CVD graphene on copper foil (green).

SEM images taken on (a) Au implanted 4H-SiC, (b) Si implanted 6H-SiC, and (c) graphene nanoribbon surfaces. (d) TEM images taken across the Au/graphene/6H-SiC.
