Title: Tunnel transistor and storage circuit
Inventor: BABA TOSHIO
IPC: H01L29/78
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a tunnel transistor which has a plurality of negative resistance characteristics by providing a source electrode, a drain electrode and a gate electrode to be formed on a source, a drain and an insulation layer. SOLUTION: When a positive voltage is applied to a drain electrode 8, three n<+> -p<+> tunnel junctions in all between each left edge of P<+> -GaAs connecting areas 9 and the left edge of a P<+> -GaAs drain 3 and channel layers 4 are permitted to be the forward-direction bias wherein negative resistance appears. Two n<+> -p<+> tunnel junctions between the right edge of the p<+> -GaAs connecting areas 9 and the channel layers 4 are permitted to be reverse-direction bias which has low resistance characteristics. Thus, among the n<+> -P<+> tunnel junctions, three tunnel junctions are forward-direction bias, and the two tunnel junctions are reverse-direction bias.  Since reverse-direction bias tunnel junction has extremely low resistance compared with forward-direction bias tunnel junction, current between the source 2 and the drain 3 is decided by the tunnel junction characteristics of the high resistance forward-direction bias, and three negative resistance characteristics are permitted to continuously appear.
