The conductivity of single walled nanotube films in Terahertz region

The conductivity of single-walled nanotube films is investigated with a combination of Maxwell-Garnett (MG) and Drude-Lorentzian (DL) model in terahertz region. A theoretical investigation for the recent experiment is given and a decrease of the real conductivity with increasing frequency is predicted. Meanwhile, the real part of dielectric function of single-walled carbon nanotube films is displayed

The magneto-optical Kerr effect of InSb in Terahertz region

A theoretical investigation for the magneto-optical Kerr effect of InSb in Terahertz region is carried out. The results show an enhancement of Kerr effect both at room temperature and a low temperature in Terahertz region. The enhancement of Kerr spectrum due to the plasma edge effect is put forward. Meanwhile, the magneto-optical Kerr effect spectrum of InSb in the different external magnetic fields are discussed. The peak shifts of the Kerr rotation under different external magnetic fields and temperatures are discussed.
