Diamond has become an attractive material not only for fundamental research but also for industrial uses due to the extraordinary combination of its intrinsic properties. Its chemical vapor deposition is routinely done over the world on a large varie

We present technological issues in the deposition of diamond films on the GaN membranes. Many wrinkles and the thicker diamond layer were observed at the membrane centre and poor quality diamond outside the membrane area. The deflection of the membra

The following materials based on four allotrope types of nanocarbons were investigated: (1) fullerene C60 and hybrid C60/Ti films, (2) composites of synthetic polymers and carbon nanotubules (i.e., carbon nanohorns and carbon nanotubes), (3) graphene

The potential uses of diamond films can be found in a diverse range of industrial applications. However, deposition of diamond films onto some foreign materials is still not a simple task. Here we present the growth of adherent diamond films on coppe

Spin coating of PVA polymer with fine grained diamond powder is used as the nucleation treatment for achieving growth of nanocrystalline diamond (NCD) thin films. The growth is realized by standard microwave plasma chemical vapor deposition (CVD). Th
