Abstract

An embodiment of the present invention discloses a method for controlling a current path range by using electric field, the method for controlling a current path range comprising: a step for applying electric field to an active layer via an application electrode to form a polarized region in the active layer, wherein the active layer includes a spontaneous polarization material, and the application electrode is disposed adjacent to the active layer; and a step for forming a variable low resistance region corresponding to the boundary of the polarization region. The variable low resistance region is a region that has a lower electrical resistance than other regions adjacent to the variable low resistance region among the regions of the active layer, and thus enables the formation of an electric path.
