|Abstract:||A composite step-graded collector of InP/InGaAs/InP DHBT has been investigated for minimised carrier blocking. The optimised collector has the following sub-layers: a 100Å n- InGaAs layer; three 200Å n- InGaAsP layers; and a 100Å, n = 3 × 1017cm-3 InP layer, and the rest are n- InP. The InGaAsP layers should be chosen to give approximately equal band offset at the heterointerfaces.|
