Role of Strontium in Oxide Epitaxy on Silicon

The reaction of strontium with the silicon (001) surface is a unique step in creating atomically sharp crystalline oxide/silicon heterostructures. We have found, through a combination of first principles theory and experimental diffraction studies, a previously unidentified surface phase. This result resolves several unanswered questions about why very few recipes to grow crystal oxides on silicon are successful.
