Abstract

Non-ohmic transport was studied by pulse method in the charge-ordered state of the organic conductor θ-(BEDT-TTF)₂CsZn(SCN)₄ as controlling the electronic state by uniaxial strain method. It was discovered that the non-ohmic conduction under high electric fields lead to the meta-stable state with a structural modification, where the ohmic resistance was reduced to be smaller than the original. The response of the CO state to pulsed electric fields suggested a possible internal deformation of the ordered charge's lattice.
