摘要
Quasiballistic electron transport in the InGaAs base of an npn HBT with an InP tunnel injector has been observed for the first time using the technique of hot-electron spectroscopy. Electrons injected from the emitter which are not scattered retain a narrow energy distribution after traversing the base. The contribution of the quasiballistic electrons to the total collector current has also been estimated.
