Abstract
Provided is a negative differential resistance element having a 3-dimension vertical structure. The negative differential resistance element having a 3-dimension vertical structure includes: a substrate; a first electrode that is formed on the substrate to receive a current; a second semiconductor material that is formed in some region of the substrate; a first semiconductor material that is deposited in some other region and the first electrode of the substrate and some region of an upper end of the second semiconductor material; an insulator that has a part vertically erected from the substrate, the other part vertically erected from the second semiconductor material, and an upper portion stacked with a first semiconductor material; and a second electrode that is formed at an upper end of the second semiconductor material to output a current, thereby significantly reducing an area of the device and greatly improving device scaling and integration.
