FIG. 1.

(a) Illustration of the present CVD process and the three different cooling processes after the reaction. The temperature of substrates was changes (i) from 900 to within 10 s (flash cooling), (ii) from 900 to around 70 s (natural cooling) and then to 600 within 10 s (flash cooling), and (iii) from 900 to around 15 min (natural cooling). (b) Raman spectra of the surface of Ni substrates after [(i)–(iii)] each cooling processes and (iv) reannealing of graphenes on Ni at for 5 min under Ar atmosphere (same to CVD condition except no ethanol flow). (c) Raman maps of the FWHM of 2D (around ) band on a nickel substrate. Scale bar is .
