摘要：

Using THz time-domain spectroscopy (THz-TDS), we have measured the absorption and dispersion of 7.5/(Omega 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.
