    Notes: Summary Ellipsometric measurements on TaSi2 polycrystalline films are presented in this paper. The optical functions are directly obtained in the wavenumber range from 400 to 3000 cm−1 using an infrared ellipsometer coupled with a Fourier transform spectrometer. The analysis of the results provides the spectral range where the infrared response has a Drude-like behaviour. Finally, the optical resistivity at zero frequency is evaluated from the Drude parameters.

    Description / Table of Contents: Riassunto In questo lavoro sono riportati e discussi gli spettri di riflettanza (R) e termoriflettanza (TR) in infrarosso di campioni di silicio drogati pesantemente per diffusione con P e B. Dai dati sono ricavati i valori dei tempi di rilassamento e della massa effettiva, come pure la derivata in temperatura della frequenza di plasma, del tempo di rilassamento e della costante dielettrica ad alta frequenza, che sono analizzati sulla base delle interazioni fra portatori liberi e fononi e fra portatori liberi e impurezze.
    Notes: Summary In this work reflectance (R) and thermoreflectance (TR) spectra in the infra-red of bulk P and B heavily doped silicon samples are reported and discussed. The values of the scattering time and of the effective mass, as well as the temperature derivative of the plasma frequency, scattering time and high-frequency dielectric constant are extracted from the data and analysed in terms of free-carrier-photon and free-carrier-impurity interaction.
