Abstract
Recently, electron self-organizations and/or inhomogenizations accompanying giant responses have attracted a keen interest in various fields of condensed matter. This is called "intrinsic inhomogeneity" in the sense that it is formed independently of lattice inhomogeneity. An organic conductor θ-type BEDT-TTF salt is a nearly perfect crystal with very little disorder, and exhibits giant nonlinear conduction together with inhomogeneity of charge order. Here we will briefly review this phenomenon in terms of intrinsic inhomogeneity.
