Outline of Final Research Achievements |
In this research, we investigated the characteristic non-linear electronic properties appearing in the strongly correlated electrons coupled with soft molecular lattice system in organic conductors possessing characteristic charge-spin-lattice multiple-degrees of freedom. We found that the novel charge-glass state existed around the charge-order insulating transition (electrons solid-liquid transition) in a molecular conductor. This charge glass state is the third electronic state, in addition to the electrons solid (insulator) and electrons liquid (metal), which indicates heterogeneously quenched solidification of electrons with quite slow time-scale of the electronic dynamics.
