Kód oboru RIV: BI - Akustika a kmity

The laser acoustic method was used for analysis of two layered systems: thin titanium and diamond like carbon films both deposited on silicon. The film and substrate parameters are determined by fitting the theoretical curve to the measured dispersion curve. The fit software seeks that set of the system parameters whose theoretical curve coincides the best with the experimental data. For the titanium film the best root-mean square deviation was 2.04 m/s with the relative error < O.I % and for the DLC system the corresponding value was 0.30 m/s (the relative error < O.O1 % ).
