Term (Index) Definition
base transport factor  factor defining efficiency of minority carrier transport through the base of a bipolar transistor, i.e. from the emitter junction to the collector junction; should be as close to 1 as possible.
bipolar transistor, BJT  Bipolar Junction Transistor; a transistor consisting of three semiconductor regions (emitter, base, and collector) with alternating conductivity type (i.e. n-p-n or p-n-p); current flow comprises both majority and minority carriers (hence, "bipolar"), is controlled by vertical dimensions; current controlled device; key transistor structure in semiconductor electronics.
base width  distance between metallurgical emitter and collector junctions in bipolar transistor; key geometrical feature of the bipolar transistor defining its peformance; narrower the base more efficient transfer of minority carriers from the emitter to collector across the base, and hence, better performing transistor.
