For the films prepared with reactive gas flows higher than 10 sccm (zone T), the results of composition analysis revealed the presence of over-stoichiometric films, where the non-metal to metal atomic ratio varies from 1.17 to 1.44 (Table 1), and thus
indicating the possibility to form different crystalline structures beyond the previously mentioned ZrN films. The sample prepared with a gas flow of 10 sccm seems to present already another phase, which is evident in the large broad peak around
2θ= 30°, becoming even more pronounced in the sample prepared with 13 sccm (Fig. 1). For this sample, the diffraction data reveals also a broad peak located at 2θ≈32.2°
