| Description | We report on far-infrared ellipsometric measurements of Si:P with the phosphorus concentration at the metal-insulator (MI) transition, for temperatures from 15 to 300 K in the 50-600 cm-1 spectral range. Temperature coefficients of the complex conductivity have been measured with high resolution; they reveal a nontrivial evolution of the optical response. |
