Abstract:
1. A transistor, comprising: a tunnel junction structure and a gate electrode, wherein said tunnel junction structure comprises: a tunnel barrier formed of a ferromagnetic material; a source formed of a ferromagnetic material; and a drain formed of a nonmagnetic material or a ferromagnetic material, said tunnel barrier being disposed between said source and said drain, the source being joined to one end surface of said tunnel barrier, and the drain being joined to the other end surface of said tunnel barrier, wherein said gate electrode is formed over said tunnel barrier and applies an electric field to the tunnel barrier; the tunnel barrier has a thickness so that Fowler Nordheim tunneling from the drain to the source does not occur in the case that said gate electrode does not apply the electric field to the tunnel barrier and occurs in the case that said gate electrode applies the electric field to the tunnel barrier.
