Far-infrared reflectivity spectra of (100) SrTi1−xNbxO3 single crystal have been measured under different temperatures in the frequency region between 100 and 6000cm−1. The obtained spectra are analyzed based on the double damping extended Drude model. Extra absorption near the highest frequency lon...
