WEST LAFAYETTE, Ind. – An innovation by Purdue University researchers could help the semiconductor industry design transistors that are smaller, use less power and switch from on to off at smaller applied voltages. As a result, the innovation could lead to better and more powerful central processing unit generations, which can compute more operations with less energy.

Tillmann Kubis is the Katherine Ngai Pesic & Silvaco Research Assistant Professor of Electrical and Computer Engineering in Purdue’s Elmore Family School of Electrical and Computer Engineering. He said it has become more difficult to meet the performance requirements of nanotransistors.

“They need a high enough ON-current and low enough OFF-current, with a small enough difference to switch between both,” Kubis said. “These challenges have significantly slowed the downscaling of transistors around the last eight years, making it increasingly difficult to…
