Claims19
A two-terminal device comprising:
- a first terminal;
- a second terminal;
- and
- a diffusion current element including an insulating layer, and configured to prevent generation of leakage current by generating diffusion current due to a potential barrier of the insulating layer depending on voltage environment between the first terminal and the second terminal,
- the diffusion current element comprising
- the insulating layer;
- a first electrode corresponding to the first terminal, and formed on the insulating layer;
- a second electrode corresponding to the second terminal, and formed on the insulating layer to be separated from the first electrode;
- diffusion electrodes separated from one another and arranged in a line on the insulating layer between the first electrode and the second electrode, and configured to form multiple channels for transferring the diffusion current;
- and
- a control electrode formed with respect to the insulating layer,
- wherein the control electrode is electrically connected to at least one of the first electrode and the second electrode, and
- wherein each of the multiple channels amplifies the diffusion current having directionality depending on the voltage environment.
