Formation of graphitic carbon nitride and boron carbon nitride film on sapphire substrate

Japanese Journal of Applied Physics, 2018
As a novel production method of boron carbon nitride (BCN) films, in this paper, we present the incorporation of B into graphitic carbon nitride (g-C3N4). First, we investigated the formation of g-C3N4 films via chemical vapor deposition (CVD) using melamine powder as the precursor.

Solid‐state Carbon Nitrides

Advanced Materials, 1997
AbstractWhether crystalline or amorphous sp3‐bonded carbon nitrides containing substantial amounts of nitrogen can be synthesized remains an open question. Various deposition techniques and high pressure syntheses to 40 GPa have not been successful thus far.

Carbon nitride film deposition by active screen plasma nitriding

Materials Letters, 2011
Abstract Deposition of CN-based films by a novel version of active screen plasma nitriding, aiming at surface modification of polymers, is reported. The approach relies on the use of pure graphite as the grid material, which was found to act both as an active screen and as a dry source of carbon atoms for the synthesis of thin films consisting mainly

Silicon Nitride – Carbon Nanotube Composites

Materials Science Forum, 2007
Multiwall carbon nanotube reinforced silicon nitride composites have been prepared by hot isostatic pressing. A manufacturing process has been worked out to avoid the damage of nanotubes during sintering. This method provides their preservation even in severe circumstances at temperature 1700°C and gas pressure 20 MPa.

Magnetron sputtered carbon nitride films

Surface and Coatings Technology, 1994
Abstract Carbon nitride (CN x ) thin film deposition was undertaken in a closed-field, unbalanced magnetron system. Reactive deposition utilised a graphite target in an argon/nitrogen plasma. The main deposition parameters investigated were magnetron current, total gas pressure and nitrogen gas partial pressure.

Photoluminescent carbon nitride films grown by vapor transport of carbon nitride powders.

Chemical communications (Cambridge, England), 2002
The thermal vapor transport of nitrogen-rich carbon nitride powders produces carbon nitride films on substrates that retain significant nitrogen content, have conjugated bond character, and show blue photoluminescent emission near 450 nm.
