Erratum: "X-ray reciprocal space mapping of dislocation-mediated strain relaxation during InGaAs/GaAs(001) epitaxial growth" [J.The driving force of ͗100͘ dark-line defect ͑DLD͒ climbing growth based on vacancy unsaturation is discussed. In In x Ga 1Ϫx As/GaAs strained structures, it is found that compressive strain can reduce the osmotic ͑climb͒ force and can suppress the climb of DLDs in ͗100͘ direction. The percentage of indium in In x Ga 1Ϫx As/GaAs strained heterostructures for the suppression of ͗100͘ DLD propagation is calculated under different material growth temperatures and doping levels. For an n-type doping level higher than 5ϫ10 16 cm Ϫ3 , an indium percentage less than approximately 9% in In x Ga 1Ϫx As/GaAs heterostructures is sufficient to stop the ͗100͘ DLDs growth and agrees well with the experimental observation. These results are useful for the design and fabrication of high reliability strained heterostructure devices.
