| Outline of Final Research Achievements |
Current-voltage characteristics in insulators attached to metallic electrodes have been studied theoretically. For an organic conductor beta-(meso-DMBEDT-TTF)2PF6, which exhibits an insulating state with charge order, I have investigated how the applied bias destroys the charge-ordered insulator when the current flows. I found that a novel bias-induced conductive state in which the charge-order remain finite. I also clarified conditions for the appearance of negative differential resistance in systems with electrodes by studying a simplified model exactly.
