Publication of a recent study on epitaxial hafnia films
A paper has recently been published in Nanomaterials as a result of our collaboration with the Instituto de Nanociencia y Materiales de Aragón. In this study, the demonstration that high quality epitaxial Hf0.5Zr0.5O2 films can be grown directly on C- oriented corundum substrates with a non-centrosymmetric orthorhombic structure, whose polar nature has been corroborated by pyroelectric measurements, contributes to the understanding of the mechanisms of the epitaxial stabilization of the ferroelectric phase of hafnia.
