Investigation of titanium nitride films prepared by ion-beam-assisted deposition at high Ar+/Ti ratio

Abstract

ABSTRACTTitanium nitride films were prepared by reactive ion beam assisted deposition (RIBAD) with Ar+/Ti ratios ranging from 1.0 to 2.3. The compositions, phases and textures of these films were studied by AES and XRD as a function of Ar+/Ti ratio and nitrogen partial pressure. The results indicate that the IBAD titanium nitride films deposited at high Ar+/Ti ratio and low nitrogen partial pressure may have reduced nitrogen concentration, (200) preferred orientation, and possibly contain the Ti2N phase.
