Heusler compounds are a promising class of thermoelectric materials that can convert waste heat into electricity. Importantly, they are composed of Earth-abundant elements. Their efficiency depends sensitively on electronic structure, however, challenges in preparing high quality single crystalline samples have inhibited such measurements. Now, as part of a SEED project within the Wisconsin MRSEC, scientists have directly measured the electronic structure of high electron mobility (500 cm2/Vs) FeVSb thin films, using angle-resolved photoemission spectroscopy (ARPES). Surprisingly, the valence band of this material is narrower and the effective mass is higher than predicted by density functional theory calculations. These results call for a re-examination of our understanding of the electronic structure in these materials, and in particular, the potential role of electron-electron correlations.

Industry outreach efforts of the Wisconsin MRSEC are facilitated by the Advanced Materials Industrial Consortium (AMIC).

The Wisconsin MRSEC's fourth annual Facilities Day Open House, held on April 12-13, 2018n engaged 165 scientists, engineers, students, instrument vendors, and employees of local companies.

The Share Instrumentation Facilities of the Wisconsin MRSEC provide access to and training on over 100 state-of-the-art instruments for fabrication and characterization of m materials. They are widely used by University of Wisconsin students and staff, researchers from other universities, and representatives of companies throughout the region.

The “Informatics Skunkworks” is a group dedicated to engaging undergraduates in realizing the potential of informatics for science and engineering. Skunkworks participants work together in project-based research, learning critical skills in teamwork, presentation, project management, software development, and applied data science, as well as driving data-centric approaches poised to transform the future of science and engineering. Everyone is welcome.

The Wisconsin MRSEC has developed research-inspired educational digital games that are each being played over 1900 times/week. Atom Touch teaches students about atom behavior, bonding, and forces. Crystal Cave lets students explore how molecules form repeating patterns to grow into large crystals. During development, local K-12 teachers provided input on how to make the games more engaging for student learning.

Over 90 people attending the 2017 Materials Research Society (MRS) Fall meeting practiced their science communication skills during two interactive, improv-based workshops presented by the Wisconsin MRSEC. The workshops were based upon the highly successful Improv to Improve Science communication and Teaching course for graduate students that Wisconsin MRSEC members co-developed with a Madison theater company and teach at UW-Madison. The workshops were designed to help MRS members practice communication skills, interact with audiences, and collaboratively develop an elevator pitch for their own research projects. The workshop can be adapted to various time constraints, workshop objectives, and numbers of attendees and has been presented over a dozen times at UW-Madison.
