Stress and Strain of GaAs on Si Grown by MOCVD Using Strained Superlattice Intermediate Layers and a Two-Step Growth Method

Abstract
The stress and strain of GaAs on Si grown by using strained superlattice intermediate layers and a two-step growth method are characterized by the photoluminescence, X-ray diffraction and the curvature radius. The strain of GaAs grown using strained superlattice intermediate layers is smaller than that grown by the two-step growth method.
