A team of researchers led by a University of Arkansas professor will use a $10.35 million federal grant to establish the first Energy Frontiers Research Center in Arkansas, according to a news release. press of Tuesday, September 20.

The Atomic Orders Manipulation Center for Semiconductor Fabrication will study the formation of atomic orders in semiconductor alloys and their effects on various physical properties. The research should enable reliable, cost-effective and transformative manufacturing of semiconductors, the essential material used in computers and other electrical devices.

The four-year grant from the U.S. Department of Energy is part of the agency’s $540 million in research funding for universities and national laboratories focused on clean energy technologies. The goal is to create and develop low-carbon manufacturing processes that will reduce greenhouse gas emissions.

According to the release, the award is based on the research team’s recent discovery that atoms in the silicon-germanium-tin alloy, a semiconductor material, exhibit short-range order in a periodic lattice. Short-range order refers to the regular and predictable arrangement of atoms at short range, usually one or two atom spacings apart. This discovery had a significant effect on the energy bandgap and led to the hypothesis that material properties in semiconductor alloys could be designed and fabricated by manipulating the order of atoms.

The research team will be led by Shui-Qing “Fisher” Yu, professor of electrical engineering at UA, and includes four colleagues from the physics department: Distinguished Professor Greg Salamo, Assistant Professor Jin Hu, Associate Professor Hugh Churchill and Assistant Professor Hiro. Nakamura. The team also includes several researchers from other institutions, including Arizona State University, George Washington University, Stanford University, University of California, Berkeley, Dartmouth College, Rensselaer Polytechnic Institute, University of Arkansas Pine Bluff, University of Delaware and Sandia National Laboratory.

According to Yu, the center is already operational and existing lab space on the AU campus will include the center. Plans are not underway for a new building to house the center.
