Abstract
A series of GaAs/InAs/GaAs samples were studied by double crystal X-ra y diffraction and the X-ray dynamic theory was used to analyze the X-r ay diffraction results. As the thickness of InAs layer exceeds 1.7 mon olayer, 3-dimensional InAs islands appear. Pendellosung fringes shifte d. A multilayer structure model is proposed to describe the strain sta tus in the InAs islands of the sample and a good agreement is obtained between the experimental and theoretical curves.
