| Outline of Final Research Achievements |
In this research, we investigated the electric noise detection and the large charge response from the electric noise induced by the charge dynamics of pi-electrons coupled to the molecular structure dynamics from the proton-motion, the ethylene-rotation and so on. We obtained several results in the study of noise experiments of molecular materials; the large enhancement of the 1/f-noise coupled to the dielectric anomaly in the dimer-Mott insulator, the appearance of the broad band noise from the growth of the charge cluster in the charge glass molecular material and the quantum effect in the inter-coupling between the proton motion and the charge transfer in the supra-molecule.
