Abstract
Convergent beam electron diffraction (CBED) performed on plan-view sam ples has been considered in order to analyse strained superlattices. T he composition modulation along the growth axis of multilayer material s and the strain modulation at the interfaces give rise to special fea tures in higher order Laue zone (HOLZ) reflections. A simple model bas ed on the expansion-contraction of the lattice spacing in each layer a long the growth direction is proposed to simulate rocking curves in th e kinematical approximation. Applications to CdxZn1-xSe/ZnSe superlatt ices are discussed.
