Low temperature crystallization of diamond-like carbon films to graphene
by low energy plasma surface treatment    [PDF]

Plasma surface modification was used to fabricate graphene on the top of insulating diamond-like carbon films. It is shown that by a combination of pulsed argon plasma treatment and thermal annealing at 350\degreeC is possible to achieve partial crystallization of amorphous carbon to graphene. The observed Raman spectra are typical for defected graphene - splitted D- and G-peaks and a broad 2D-peak. This result is very encouraging and we hope that by improving this technology it will be possible to fabricate defect-free graphene, which can be used in electronics without transfer to other substrates.
