Study of fundaments of proton transfer high fast optical switch using microwave microscope

研究了在质子转移及相关材料中初步观察到的微波电导率随温度变化的巨滞现象的原因。我们试图通过宏观和局部微波电导测量来阐明磁滞现象的原因，并基于这些材料中的质子转移机制来开发新型的快速光开关。然而，我们没有发现任何明确的证据表明，磁滞是与质子转移有关的相变的表现。然而，在这些研究中，我们成功地获得了新的质子转移材料，这是一种新的很好的快速光开关候选材料。为研制用于局部电导率测量的高精度微波显微镜找到了一条明确的途径。

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.
