Abstract-Magneto-optical properties of InSb for terahertz applications
tensor spectra of undoped n-doped and p-doped crystals were determined using the terahertz time-domain spectroscopy (THz-TDS) and the Fourier transform far-infrared spectroscopy (far-FTIR). A Huge polar (MO) Kerr-effect (up to 20 degrees in rotation) and a simultaneous plasmonic behavior observed at low (0.4 T) and room temperature are promising for terahertz nonreciprocal applications. We demonstrate the possibility of adjusting the the spectral rage with huge MO by increase in n-doping of Spectral response is modeled using generalized Drude-Lorentz theory, giving us precise values of free carrier mobility, density and consistent with electric Hall measurement.
