Popis: A theoretical investigation of double-heterojunction bipolar transistors (DHBTs) based on the layered N+-N-n-N-N+ heterostructures in the III-V material system with acceptor delta-layer near an emitter N-n interface has been undertaken in an attempt to determine the peculiarities of their current-voltage characteristics. It has been shown that intervalley scattering in narrow-gap n-type base layers results in negative difference conductance.
