Defect suppression from the compound semiconductor heterointerfaces
We report on the effect of inserting ultra-thin InAs layers at the heterointerfaces on physical properties of GaAs/InGaP on GaAs and InP/GaAs on InP grown by MOCVD and MOMBE, respectively. It is shown that the insertion of ultra thin InAs layers at the heterostructure interfaces has a significant effect in eliminating defects from the interfaces.
