摘要:
A defect characterization of two highly lattice-mismatched semiconductor heterostructures (InAs/GaAs and GaP/GaAs) grown by Atomic Layer Molecular Beam Epitaxy has been performed by Transmission Electron Microscopy. The experimental results show that layers grown under compression exhibit a lower planar defect density than those grown under tension. This behaviour can be explained by the dissociation state of dislocations which depends on the sign of the stress in each layer.
