Boron nitride thin layers were fabricated by the pulsed laser deposition technique using a KrF excimer laser. In order to improve stoichiometry, a radio frequency discharge generator was additionally applied. Increase of the substrate temperature from 20 to 700 degrees caused an increase of content of crystalline sp²-bonded phases and changes in the surface morphology. The deposition of a BN coating at 700˚C produced a layer with a nano-composite microstructure, consisting of nano-crystaline w-BN particles embedded in a t-BN and h-BN matrix.

Boron-nitridové vrstvy byly připravené laserovou depozicí v kombinaci s RF výbojem. Při zvýšení teploty podložky od 20 st. Celsia do 700 st. Celsia byla pozorována nanokrystalická struktura w-BN zabudovaná v t-BN a h-BN matrici.
