Reflectivity Spectra

An "extended-Drude" model, implying a simple form for the self-energy function of the mobile charge-carrier response, has been applied to fitting the infrared and visible reflectivity spectra of simple cuprates. Excellent fits are obtained in a wide spectral range, from 4 meV to 4 eV, with a very restricted number of adjustable parameters. The optical conductivity obtained with this procedure is highly different from the Kramers–Kronig transformation of reflectivity spectra. The same procedure has been applied to characterise the infrared conductivity of multi-target laser-ablated films built via intergrowth of YBa2Cu3O7 and MCuO2 (M = Ca, Sr).
