Outline of Final Research Achievements

We have tried to develop a new terahertz time-domain spectroscopy system with optical fibers for high magnetic field and low temperature measurements. We also carried out the cyclotron resonance in InGaAs and CdMnTe quantum Hall systems, Graphene and a topological insulator under high magnetic field with the use of the vector network analyzer, the Gunn oscillators and the FT-IR spectrometer. Various new aspects of the cyclotron resonance were observed in our present investigation.
