Abstract

We have studied the morphology of antiphase boundaries (APBs) and their formation mechanism in CuAu-I type ordered InGaAs grown on a vicinal (110)InP substrate. In InGaAs grown at 380°C, APBs are formed parallel to (110) by the flow of one-monolayer steps. In InGaAs grown at 450°C, the normal directions of APBs arc slightly tilted toward [011] or [001] from (110) and some APBs show a hairpin shape. New formation mechanisms of these APBs are proposed.
