Abstract

The strain field of an edge dislocation in silicon was experimentally investigated. High-resolution transmission electron microscopy and geometric phase analysis were used to map the strain fields of the edge dislocation. The strain measurement results were compared with the Peierls-Nabarro dislocation model. The comparison shows that the Peierls-Nabarro model is an appropriate theoretical model to describe the strain fields of edge dislocation in silicon.
