Abstract

In our earlier published work, we have shown that there is a composition range of the (Ti1-xAlx)1-yYyN alloy films (0.72 at a certain thickness forming a definite crossover. Moreover the c-TiN and the w-AlN〈0001〉 crystals were epitaxially related with axes tilted to the direction of the vapour beam.Based on a comprehensive transmission electron microscopy (TEM) and diffraction (XRD and selected area electron diffraction (SAED)) structure and morphology analysis, we discovered the details of this exotic structure making it possible to construct the complex pathway of structure evolution including the formation of the w-AlN phase and the change of the dominating texture of c-TiN phase with thickness in dependence of the Ti/Al ratio and the deposition parameters. This pathway could be deduced from the fundamental phenomena of structure formation and may be generalised for multi-component thin film systems. A composition structure zone model has been also proposed for the (Ti1-xAlx)1-yYyN thin film system in the 0
