Dr. Comes’ paper in collaboration with Steven Spurgeon and Daniel Perea at Pacific Northwest National Laboratory has been published in Advanced Materials Interfaces. In this paper we demonstrate the first growth of an epitaxial oxide nanocomposite by molecular beam epitaxy (MBE). Almost all of the previous work had focused on depositing materials by pulsed laser deposition, with separate sources of spinel material (in this case NiFe2O4) and perovskite material (LaFeO3 here). When we do the growth by MBE, instead we have to provide elemental La, Fe, Ni, and O and allow the phases to form on their own. We find that the same thermodynamics apply, but that the kinetics of how the nanocomposites grow are a bit different. Using state-of-the-art atom probe tomography and scanning transmission electron microscopy measurements of the same region of a sample, we are able to understand how the phases segregate and get a 3-dimensional model of what forms at the end. This should pave the way for studies of new combinations of materials and new morphologies of these interesting nanocomposites.
