CO2 laser induced decomposition of 3-butyn-2-one in the gas phase resu
lts in the deposition of carbonaceous films composed of a graphitic an
d monohydrogenated carbon, in which H is dominantly bonded to sp(3) si
tes. The films incorporate oxygen in superficial layers. The technique
is suitable for preparation of thin C-based films at low substrate te
mperatures. (C) 1998 Elsevier Science Ltd. All rights reserved.
