Abstract :
Free carrier Faraday and Voigt effects are studied using terahertz time domain transmission spectroscopy (THzTDTS). The frequency dependence of Faraday ellipticity and Faraday rotation are deduced from the experimental data and show good agreement to theoretical calculations based on the Drude model. Voigt ellipticity also shows good agreement to theory and is found to be considerably smaller than that of Faraday ellipticity.
