Query: Low temperature crystallization of diamond-like carbon films to graphene
  by low energy plasma surface treatment   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.
