The optical response functions were obtained from the reflectivity spectra by means of the Kramers-Kronig analysis with the appropriate low- and high-frequency extrapolations of the experimentally determined reflectance. The reflectance spectra were fitted by Drude-Lorentz model in order to obtain temperature dependence of the model parameters. The fits were consistent with the optical response functions. A significant drop of the Drude free-electron term was observed under Tc. Pracoviště Fyzikální ústav Kontakt Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Rok sběru 2011
