Abstract:

The exponential growth of electronic devices and data processing has pushed charge-based electronics to their energy and performance limits, with power consumption and heat dissipation becoming critical bottlenecks. As Moore’s Law approaches its limits, there is an urgent need for a paradigm shift in our approach towards the next-generation electronic device for computing. With recent advances in materials and device engineering, spintronics is poised to overcome the limitations of traditional electronics, driving the next generation of energy-efficient and high-performance computing technologies. Here, I investigate spintronics and spin-wave platforms as transformative solutions for high-speed, low-energy electronic devices for next-generation computing. I demonstrate how the collective dynamics of spin waves can be harnessed to realize essential computing building blocks, including communication links, transistors, and memory elements, paving the way for spin-based computing platforms.

Hossein Taghinejad is a postdoctoral fellow at the School of Physics, University of California, Berkeley, where he conducts research in the Quantum-Material Laboratory of Prof. James Analytis. He holds the Heising-Simons Junior Fellowship of the Kavli Energy NanoScience Institute (ENSI) since 2022, and the Innovation Fellowship of the Bakar Technology Hub since 2021, both at UC Berkeley. Hossein earned his PhD in Electrical and Computer Engineering from the Georgia Institute of Technology, under the supervision of Prof. Ali Adibi. His PhD thesis earned him the Sigma Xi award in 2021 which recognizes the best PhD thesis of the year at the Georgia Institute of Technology. When he's not working on the spin of electrons in spintronic devices, he finds solace in spinning a soccer ball on the field, wondering when Manchester United will once again find its former glory.
