(2018) IRG2: Lanthanide Atomic-Layer Deposition: Towards New Oxide Compositions and Geometries

Creating thin films using novel synthesis techniques is a key step in expanding the functionality of metal oxide materials. It is particularly important to create these oxides in new geometrical forms and with new compositions. Researchers and the Wisconsin MRSEC have developed ways to create new oxides by first synthesizing them in the amorphous form and subsequently crystallizing the deposited material, a process known as solid-phase epitaxy (SPE).

(2018) IRG2: Lateral Solid-Phase Epitaxy of a Perovskite Complex Oxide

Three-dimensional metal oxide crystals with Madison MRSEC complex structures or compositions are challenging to prepare because it is difficult to
control nanoscale phenomena underlying crystal nucleation and growth. Researchers at the Wisconsin MRSEC have now made important steps in establishing this control in so-called “perovskite” complex oxide crystals, a class of materials with useful optical and electronic properties.

(2018) IRG1: Broader Impacts of Research on Organic Glasses with Tunable Liquid-Crystalline Order

Graduate students from IRG1 of the Wisconsin MRSEC used MRSEC-developed educational materials in two Wisconsin outreach programs: Pre-college Enrichment Opportunity Program for Learning Excellence (PEOPLE) and Science Expeditions. These programs provide experiences that help students become
scientifically literate citizens and explore careers in science and engineering. The PEOPLE program has a proven record of increasing the rate at which minority and low-income high school students matriculate to colleges and universities.

(2018) IRG1: Increased stability of CuZrAl metallic glasses prepared by physical vapor deposition

One of the main drawbacks of metallic glasses is their low thermodynamic stability, which limits their formability and service life. Recently, experiments by
members of the Wisconsin MRSEC showed that organic glasses with high thermodynamic stability can be synthesized via physical vapor deposition (PVD)
onto a substrate at a controlled temperature. Now, this team of researchers has used molecular dynamics simulations to predict that the same PVD methods can enhance the stability of metallic glasses.
