Lattice parameters of the GaAs islands as a function of island-height/growth time. The evolution of in-plane (triangles) and out-of-plane (squares) lattice parameters are shown. Along the in-plane direction, the lattice parameter increases faster during the initial stage of growth (sample A1). Dotted lines are guides to the eye.
