Convergent Beam Electron Diffraction Analysis of Strain in Multilayer Structures: A Kinematical Approach
Daniela Manno et Saverio MongelliDipartimento di Scienza dei Materiali, Università di Lecce, Via Arnesano, 73100 Lecce, Italy
Abstract
onvergent beam electron diffraction (CBED) performed
on plan-view samples has been considered in order to analyse strained
superlattices.
The composition modulation along the growth axis of multilayer materials
and the strain modulation at the interfaces give rise to special features in
higher order Laue zone (HOLZ) reflections. A simple model based on the
expansion-contraction of the lattice spacing in each layer along the growth
direction is proposed to simulate rocking curves in the kinematical
approximation. Applications to
superlattices are
discussed.
