Researchers address semiconductor energy crisis with NSF-funded projects
Weigang Wang and his collaborators in the University of Arizona Spin Lab fabricate computer chips that store information even when their power source is removed.
The National Science Foundation – as part of its Future of Semiconductors, or FuSe2, program – recently awarded $3.8 million for two projects involving University of Arizona engineers developing solutions for the semiconductor energy dilemma. Energy use in technology with semiconductors – from data centers, computers and smartphones to solar cells, electric vehicles and medical equipment – has doubled every three years since 2010, according to the U.S. Department of Energy. And these products could consume nearly 20% of the world's energy by 2030.
Marwan Krunz, Regents Professor of Electrical and Computer Engineering, is contributing to a microchip, or collection of semiconductors, expected to increase energy efficiency by 10 to 100 times and improve next-generation wireless communication. The Kenneth Von Behren Endowed Professor leads the U of A WISPER center, established in October to improve NextG functionality and security. Krunz received $575,000 for his team's part in the FuSe2 project, which Arizona State University is leading.
Weigang Wang, professor of physics and ECE, is leading development of novel materials and devices to substantially reduce energy waste, make computer memory systems up to 100 times faster, and enable further miniaturization of electronic devices. The U of A is receiving $1.1 million of the project's total award.
"The teams are tackling core technical challenges for advanced technologies that will improve communications and computing while reducing energy consumption," said Liesl Folks, U of A vice president of semiconductor strategy and professor of ECE.
The two research projects aim to tackle key challenges in the U.S. semiconductor industry.
