Abstract :
We have used RF nitrogen plasma-assisted laser deposition. Laser ablates the graphite target while simultaneously a radiofrequency (RF) nitrogen discharge is sustained by two planar electrodes situated parallel to the plasma plume and thus ensuring additional excitation of N/sub 2/ molecules. The influence of a hollow cathode (HC) discharge was also studied. Films were characterized by wavelength dispersive X-ray analysis, SEM, XRD, XPS, FTIR spectroscopy, Raman scattering, and by scratch and microhardness testers. Nearly stoichiometric N/C ratio was measured in deposited films for PLD combined with RF+HC discharges and also for PLD combined with RF only.
