Research Abstract

Organic thyristor showing giant non-linear conduction leading particular DC-AC current conversion was caused by the melting of the charge ordering by electronic current. Since, the charge ordering can produce organic dielectric materials, the realization of melting and reordering process of the charge ordering is very important to develop organic ferroelectrics. We observed variation of the two competing charge ordering and the time constant of melting and freezing for two fold charge ordering is more than several ten msec using Synchrotron Radiation under current.
