Established in 2013, the Center for Low Energy Systems Technology (LEAST) is a microelectronics research center funded by the Semiconductor Research Corporation (SRC) and the Defense Advanced Research Projects Agency (DARPA) to support the continued growth and leadership of the U.S. semiconductor industry.  In particular, LEAST researchers are developing devices that can work at lower voltage than traditional semiconductor devices and thereby dramatically lower the power of integrated circuits.

Notre Dame leads the 12-university LEAST Center, which builds on research in tunnel field-effect transistors (TFETs) developed in the Midwest Institute for Nanoelectronics Discovery (MIND), a previously funded SRC center based at Notre Dame (2008-2012). The MIND Center provided the first demonstrations of compound semiconductor TFETs.

The LEAST research team, which includes 30 faculty and 80-plus postdoctoral researchers and graduate students at its partner universities, represents expertise in materials physics, materials growth, device physics, surface science, chemistry, density-functional theory, quantum transport, nanoscale characterization, circuits, systems, and architectures.

The universities working with Notre Dame in the LEAST Center are Purdue, Penn State, Carnegie Mellon, Pittsburgh, Cornell, Illinois Institute of Technology, University of Chicago, University of Texas Dallas, University of California Santa Barbara, University of California San Diego, and University of California Berkeley.
