ABSTRACT
Using THz time-domain spectroscopy (THz-TDS), we have measured the absorption and dispersion of 7.5/(Ω cm) conducting poly-3-methylthiophene film from low frequencies up to 4 THz. From these measurements the complex conductance that increases with increasing frequency was obtained over this frequency range. The results do not follow simple Drude theory and are not comparable with normal metal and semiconductors; the results were well fit by the localization-modified Drude theory. © 2001 American Institute of Physics.

    Amorphous GeSe2 films with Ag overlayers have been illuminated in situ in a Rutherford backscattering chamber and the evolution of the silver depth profile as a function of illumination time has been studied. The silver distribution in the doped region is found to be steplike as had earlier been...
