Amorphous ''diamond-like/quartz-like'' composites a-(C:H/Si:O) constit
ute a novel class of diamond-related materials with a number of unique
bulk and surface properties. In order to gain a more fundamental unde
rstanding of the growth and surface properties of these diamond-like a
tomic-scale composite materials we have performed an atomic force micr
oscopy investigation of the surfaces of a-(C:H/Si:O) films (deposited
on Si (001) substrates) ranging in thickness from 50 Angstrom to 5 x 1
0(4) nm.
