Abstract
An electronic device which includes, a couple of first conduction regions which are capable of confining carriers, a second conduction region having a higher energy level than those of the first conduction regions, and a first electrode for impressing a voltage on the first conduction regions, wherein when a voltage is impressed via the first electrode between the couple of first conduction regions, carriers are caused to move due to a tunneling effect from one of the first conduction regions via the second conduction region to the other of the first conduction regions, and when the voltage impressed between the couple of first conduction regions is removed, carriers are confined mainly in the one of the first conduction regions.
Claims21
An electronic device which comprises;
- a couple of first conduction regions which are capable of confining carriers;
- a second conduction region having a higher energy level than those of said first conduction regions;
- and
- a first electrode for impressing a voltage on said first conduction regions;
- Wherein, when a voltage is impressed via said first electrode between said couple of first conduction regions, carriers are caused to move due to a tunneling effect from one of said first conduction regions via said second conduction region to the other of said first conduction regions;
- and when the voltage impressed between said couple of first conduction regions is removed, carriers are confined mainly in said one of said first conduction regions.
An electronic device which comprises;
- a first conduction region and a second conduction region both of which are capable of confining carriers;
- a third conduction region wherein carriers are free to move;
- a first electrode for impressing a voltage on said first conduction region;
- and
- a second electrode and a third electrode each functioning as an input and an output for passing an electric current to said third conduction region;
- wherein either one of an insulating layer and an energy barrier layer is interposed between said first electrode and said first conduction region, between said first conduction region and said second conduction region, and between said second conduction region and said third conduction region;
- and when a voltage is impressed between said first electrode and either one of said second and third electrode, or between said first electrode and said second and third electrodes, carriers are caused to move due to a tunneling effect between said first conduction regions and said second conduction region, while the carriers are inhibited from moving between said first electrode and said first conduction region as well as between said second conduction region and said third conduction region;
- and when the voltage impressed is removed, carriers are confined mainly in either one of said first conduction region and said second conduction region.
