| Outline of Final Research Achievements |
In this research, in order to elucidate ultrafast electric field induced phenomena in nanostructured semiconductors and next-generation electronic materials, it aimed to create an ultrafast measurement method for the electric-field induced phenomena with the world's highest intensity THz pulse enhanced by metallic metamaterials. This gave us two main results. It is revealed that a subcycle response with a period shorter than the period of the THz light is demonstrated caused by a dressed state in which the THz light and the exciton (GaAs) are strongly coupled. We succeeded in observing the nonlinear antiferromagnetic resonance in the antiferromagnet by utilizing resonant magnetic field enhancement effect by high intensity terahertz pulse light source and split ring resonator (SRR).
