It is found that the strain leads to further confinement of carriers and enhancement of the anisotropy. By using the EBOM and valence-force field model, we systematically studied the microstrain effects on the electronic and optical properties of Ga(1-x)In(x)As self-assembled quantumwires (QWR's) made of short-period superlattices with strain-induced lateral ordering. Valenceband anisotropy, band mixing, and effects due to local strain distribution at the atomistic level are all taken into account.
