(April 3, 2019) — Building on the Air Force’s need to develop tech devices that require minimal charging in the field, the University of Texas at San Antonio (UTSA) is using principles in quantum science and engineering to build a graphene-based logic device. This new technology will improve the energy efficiency of battery-dependent devices from cell phones to computers.

“We are developing devices that can operate almost battery-less,” said Ethan Ahn, UTSA assistant professor in electrical engineering.

UTSA engineers are using spintronics, the study of an electron’s intrinsic quantum mechanical property called spin, to allow low-power operation with a possible application in quantum computing.
