Optical Properties Of Titanium And Zirconium Carbonitride Thin Films

The reflectivity spectra of sputtered zirconium and titanium nitride, carbide and carbonitride thin films have been studied. The data are interpreted by means of their electronic structure in a Drude-Lorentz model. The influence of the nature of the metal and of the non metals is qualitatively understood. Although no good solar absorber is reported here, this study shows that the optical profile of the ternary compounds can be tailored in a wide range between those of the binary compounds.
