| Outline of Final Research Achievements |
An aligned nanofiber (NF) was prepared using electrspinning method and the NF / nematic liquid crystal (NLC) composite was constructed. The influences of polymer material, NF volume ratio, and diameter on the electrical characteristics of NF/NLC composites were investigated. By increasing the NF volume ratio in the NF/NLC composite device, the decay time was significantly decreased. It was found that smaller NF diameter and higher NF volume ratio had a greater effect on improvement of the decay time, however, the threshold voltage of the composite device increased.
A terahertz (THz) wave phase shifter using NF/NLC compisite was demonstrated. The phase shift value of the NF/NLC composite device was almost half but the decay time was achieved approximately 1/600 of the pure NLC device. The effectiveness of THz wave device using the NF/NLC compisite was clarified.
