| Research Abstract |
Origin of the giant hysteresis in the temperature dependence of the microwave conductivity preliminary observed in proton-transfer and related materials were studied. We tried to clarify the origin of the hysteresis, by both macroscopic and local microwave conductivity measurements, and aimed to develop novel fast optical switches based on the proton transfer mechanisms in these materials. However, we did not find any definite evidences that the hysteresis was the manifestation of the phase transition where proton transfer was related. However, during those researches, we succeeded in obtaining new proton transfer materials, which are novel good candidates for fast optical switches. Also we found a definite route to develop high precision microwave microscope for local conductivity measurement.
