Abstract
A composite step-graded collector of InP/InGaAs/InP DHBT has been inve stigated for minimised carrier blocking. The optimised collector has t he following sub-layers: a 100 Angstrom n InGaAs layer; three 200 Angs trom n InGaAsP layers; and a 100 Angstrom, n = 3 x 10(17) cm(-3) InP l ayer, and the rest are n InP. The InGaAsP layers should be chosen to g ive approximately equal band offset at the heterointerfaces.
