An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The Heterojunction-emitter bipolar transistor (HEBT), is a somewhat unusual arrangement with respect to emitter blocking of minority carriers. This is accomplished by using heterostructure confinement in the emitter, introducing an energy barrier to minority-carrier charge flow from the base. This is important as loss of minority carriers from the base to the emitter degrades analog performance. The main difference of the HEBT from the Heterojunction bipolar transistor (HBT) is that the emitter–base interface is the same as in a bipolar junction transistor (BJT) with the blocking energy gap being moved back into the emitter bulk region.
