| Research Abstract |
To observe Josephson plasma resonance, we prepared bilayer samples with electrically separated electrodes for each layer. With microwaves irradiation from the gate electrode, we attempted to measure changes in the tunneling current by plasma resonance. However, we have yet to detect the signal. We will improve the measurement system and continue to try to detect Josephson plasma resonance. Advancing research regarding the quantum Hall effect related to this subject, we obtained research results in achievement of the soliton lattice phase, the excited states of fractional quantum Hall effects, anisotropic nuclear polarization, and diffusion of nuclear polarization.
