Application of the Terahertz time-domain spectroscopy to magneto-optical measurements under high magnetic field

我们建立了用于磁场下半导体低维系统磁光测量的太赫兹时域光谱技术。利用该系统在InGaAs二维电子系统中观察到了回旋共振现象。另外，在毫米波和亚毫米波区域，我们成功地观测到了具有密集二维电子浓度的量子霍尔系统的磁透射的反常量子振荡。

We have established the terahertz time-domain spectroscopy for applying the magneto-optical measurements in semiconductor low dimensional systems under magnetic fields. The cyclotron resonance was observed in a InGaAs two-dimensional electron system with using the developed system. As other results, we succeeded in observing anomalous quantum oscillation of the magneto-transmission for the quantum Hall systems with dense two-dimensional electron concentration at millimeter and sub-millimeter wave region.
