“…ABPs were first considered by Aminoff & Broome (1931). Such defects in compound semiconductors were discussed by Holt (1969) referring to an experimental study of defects in GaAs grown on Ge (Bobb et al ., 1966). Because of the technological interest in the growth of GaAs on Si and Ge for opto‐electronic and photovoltaic applications (Carter et al ., 1986; Sieg et al ., 1998; Ting et al ., 1998; Xu & Hsu, 1999a; Ting & Fitzgerald, 2000), the structure of APBs in compound semiconductors has since been the subject of numerous experimental studies (Ebert et al ., 1962; Holt et al ., 1996; Bowler & Goringe, 1998; Xu & Hsu, 1999b; Hudait & Krupanidhi, 2000).…”
