Resumen en inglés | Based on a previous developed and published one-dimensional model for the growth of metallic oxide thin films, we have studied the tridimensional growth rates for titanium dioxide films grown on Ti layers. The thermo-oxidation process of Ti films, deposited over glass substrates, is due to the film surface heating occurring when an intense beam of a pulsed Nd:YAG laser moves at constant speed on the surface exposed to air. The computational algorithm used for the calculations in this model takes into account self-consistently the heat flux equation, the Gaussian-shape laser beam, and the parabolic oxidation law starting with the initial values of the heating parameters. From these calculations we obtained a tridimensional picture of film morphology. The theoretical estimations of the film thickness and the growth ratio show excellent agreement with the measured experimental values |
