Y. Kangawa et al., Formation mechanism of antiphase boundary structure in molecular beam epitaxy grown InGaAs/(110)InP, JPN J A P 1, 38(1A), 1999, pp. 40-41
We have studied the morphology of antiphase boundaries (APBs) and their for
mation mechanism in CuAu-I type ordered InGaAs grown on a vicinal(110)InP s
ubstrate; In InGaAs grown at 380 degrees C, APBs are formed parallel to (11
0) by the flow of one-monolayer steps. In InGaAs grown at 450 degrees C, th
e normal directions of APBs are slightly tilted toward [00 (1) over bar] or
[001] from (110) and some APBs show a hairpin shape. New formation mechani
sms of these APBs are proposed.
