Sayeef Salahuddin is a Bangladeshi-American electrical engineer. He is the TSMC Distinguished Professor of Electrical Engineering and Computer Sciences at the University of California, Berkeley, and a faculty senior scientist in the Materials Sciences Division of Lawrence Berkeley National Laboratory. His research concerns negative capacitance in ferroelectric materials and its use in low-power transistor and memory devices. He is a fellow of the IEEE, the American Physical Society, and the American Association for the Advancement of Science. He also co-founded the startup Sonera Magnetics, acquired by Apple Inc. in 2026.

Early life and education

Salahuddin received a B.Sc. in electrical and electronic engineering from the Bangladesh University of Engineering and Technology in 2003, and a PhD in electrical and computer engineering from Purdue University in 2007. As a graduate student he co-authored, with Supriyo Datta, a 2008 paper proposing the use of negative capacitance in ferroelectric materials to amplify transistor gate voltage.

Career

Salahuddin joined the UC Berkeley faculty in 2008 and became the TSMC Distinguished Professor of Electrical Engineering and Computer Sciences. He co-directs the Berkeley Device Modeling Center and the Berkeley Center for Negative Capacitance Transistors, and is an associate director of ASCENT, a DARPA/Semiconductor Research Corporation device-technology center. He served on the editorial board of IEEE Electron Devices Letters (2013–2016) and later became its editor-in-chief. In 2025 he was named to the inaugural technical advisory board of the U.S. National Semiconductor Technology Center, operated by Natcast under the CHIPS and Science Act.

Research

Salahuddin's work centers on device physics for low-power electronic and spintronic devices, particularly negative capacitance in ferroelectric materials as a way to reduce transistor operating voltage below conventional thermodynamic limits. His 2008 paper with Datta proposed the underlying mechanism; later work with collaborators reported experimental evidence of negative capacitance in ferroelectric capacitors and on scaling hafnium- and zirconium-oxide ferroelectric films for transistor and memory applications, including films only a few atomic layers thick.
