Epitaxial phase-change materials



Epitaxial equation image thin layers were successfully grown in the metastable cubic phase on both slightly lattice-mismatched (GaSb) and highly lattice-mismatched (Si) templates. The higher quality of the films grown on (111)-oriented substrates is attributed to the tendency to form layered structures in the stable bulk phase as well as to the nature of distortion in the metastable cubic phase.
