A New Topological Semimetal Material May Reduce Energy Consumption in Electronics


In recently published research, three MSI PIs and their colleagues have synthesized a topological semimetal that, while using less energy than current materials, is able to generate more computing power and memory storage. Tony Low (associate professor, Electrical and Computer Engineering), K. Andre Mkhoyan (professor, Chemical Engineering and Materials Science), and Jian-Ping Wang (professor, Electrical and Computer Engineering) are senior authors on the paper, which was published in Nature Communications. New topological materials will be critical for next-generation electronic devices that are better, smaller, and more efficient than those currently in use.

An article about this research appears on the U of M News site: New materials could hold key to reducing energy consumption in computers and electronics. The paper can be found on the journal website: Robust negative longitudinal magnetoresistance and spin–orbit torque in sputtered Pt3Sn and Pt3SnxFe1-x topological semimetal.

Professor Low uses MSI for research about the physical properties of 2D materials, including electronic, optical, magnetic, and topological properties. Professor Mkoyan uses MSI resources for simulations of transmission electron microscopy in studies of technologically important materials. Professor Wang uses MSI for projects related to the search for and study of new magnetic materials.
