IPC: H01L29/66
Filed: 1991-08-28
Abstract: PURPOSE:To obtain a transistor allowing a current to flow by one electron unit besides allowing to amplify power and act stably. CONSTITUTION:A thin film 5 is formed between the emitter and the base. The junctions areas between the emitter and the base and between the base and the collector is very small. The emitter 1, the base 4 and the collector 2 are highly doped and strongly contracted at an extremely low temperature while having a pseudo-Fermi-level inside a band. A lightly doped layer each is formed between the emitter (E) and base (B) and between the bass and collector (C) so that no tunnel current may flow therebetween. The E has a wider band gap than that of the B and only electron injection E B occurrs in a forward bias between the E and the B. When the capacitor C of a thin film layer having a wider band gap than E, B satisfies e<2>C>>kBT, this electron injection occurrs one by one. This electron is accelerated by a slope electric field of the base so as to reach the collector for being accelerated by a collector electric field thus to cause voltage amplification.
