Our results indicate that the anisotropy in these materials is mostly due to the tensile strain in the GaP layers.
Introduction The progress in novel growth techniques, has made it possible to grow high quality semiconductor heterostructures and superlattices (SLs) from heavily lattice mismatched materials [1], up to a lattice mismatch of about 7% if the layers are kept sufficiently thin.
The semiconducting strained SLs are potential materials for various electronic and optoelectronic devices [2,3].
