Abstract
A method of controlling a current path range using an electric field is disclosed, and the method of controlling a current path range includes applying an electric field to an active layer including a spontaneous polarization material through an application electrode disposed adjacent to the active layer to form a polarization region of the active layer, and forming a variable low resistance region corresponding to a boundary of the polarization region, wherein the variable low resistance region is a region of the active layer having a lower electrical resistance than another region of the active layer adjacent to the variable low resistance region and allows an electrical path to be formed.

A method of controlling a current path range using an electric field, the method comprising:
- applying an electric field to an active layer including a spontaneous polarization material through an application electrode disposed adjacent to the active layer to form a polarization region of the active layer;
- and
- forming a variable low resistance region corresponding to a boundary of the polarization region,
- wherein the variable low resistance region is a region of the active layer having a lower electrical resistance than another region of the active layer adjacent to the variable low resistance region and allows an electrical path to be formed,
- the polarization region is formed to correspond to a total thickness of the active layer in a thickness direction of the active layer,
- the variable low resistance region is formed along the polarization region so as to correspond to the total thickness of the active layer in the thickness direction of the active layer,
- the variable low resistance region is not in contact with the application electrode,
- an edge of the variable low resistance region is formed so as not to overlap the application electrode in the thickness direction of the active layer,
- wherein the electric field through the application electrode is controlled to control the generation and disappearance of the variable low resistance region and accordingly to control the generation and disappearance of the electrical path.
An electric circuit comprising:
- an active layer comprising a spontaneous polarization material;
- an application electrode disposed adjacent to the active layer;
- a polarization region formed in the active layer by applying an electric field to the active layer through the application electrode;
- and
- a variable low resistance region corresponding to a boundary of the polarization region,
- wherein the variable low resistance region is a region of the active layer having a lower electrical resistance than another region of the active layer adjacent to the variable low resistance region and allows an electrical path to be formed,
- the polarization region is formed to correspond to a total thickness of the active layer in a thickness direction of the active layer,
- the variable low resistance region is formed along the polarization region so as to correspond to the total thickness of the active layer in the thickness direction of the active layer,
- the variable low resistance region is not in contact with the application electrode, and
- an edge of the variable low resistance region is formed so as not to overlap the application electrode in the thickness direction of the active layer,
- wherein an application time of the electric field through the application electrode is controlled to control a size or width of the variable low resistance region.
