Title: Versatile Electronic System

Abstract:

Within just a few years, the number of existing wireless electronic devices will be in excess of four times the world’s human population; they will be used for countless “smart” applications beyond communications, city and urban planning, and agriculture to include other applications unimaginable today. However, the functions of these devices are broad and they often have widely different requirements and tradeoffs. This research delves into the challenge of engineering devices that are highly versatile and simultaneously energy efficient and tunable to meet the ever-broadening application demands of the future.

This talk will focus on three areas in which electronics can benefit significantly from versatility: communications, haptic interfaces, and sensing. The devices discussed achieve versatility by strategically examining and utilizing the frequency-dependent and stress/strain-dependent behavior of various magnetic, piezoelectric, semiconductor, and 2D material heterostructures. Magnetoelectric (magnetic/piezoelectric) heterostructures will be presented for tunable communications; ultrafast switching of ferrimagnetic nanodots will provide localized control of tactile displays and other haptic interfaces; finally, 2D materials will be coupled with magnetoelectric composites for tunable sensing systems. Such devices will capitalize on the nanoscale interactions of diverse materials to create integrated systems that are broadly versatile, extremely energy-efficient, and self-powered, such that they can be deployed across vast agricultural landscapes, urban areas, or industrial factories without constant upkeep.

BIO:

Amal El-Ghazaly received both her B.S. and M.S. degrees in electrical and computer engineering from Carnegie Mellon University in 2011. She then earned a PhD in electrical engineering from Stanford University, where she was funded by both NSF and NDSEG graduate research fellowships until her graduation in 2016. She also received the Stanford DARE fellowship in 2015, while completing her degree. Her PhD research focused on radio frequency devices using magnetic and magnetoelectric thin-film composites for tunable wireless communications. In September 2016, she joined Professor Jeffrey Bokor's group at the University of California Berkeley as a postdoctoral research fellow and was awarded the University of California President's Postdoctoral Fellowship at Berkeley in 2017. Her postdoctoral research explored new possibilities for ultrafast all-electrical switching of magnetic nanodots for faster and more energy-efficient computer memories. In the summer of 2015, while doing her Ph.D., she interned with the Components Research department at Intel in Hillsboro, OR. She has also studied and interned abroad in Japan, Egypt, and Nigeria over the course of her undergraduate and graduate degrees. She has been a mentor with the Enhancing Diversity in Graduate Education program at Stanford, a tutor-mentor with the East Palo Alto Stanford Academy, the founder of the Berkeley STEM Fam diversity series, and a leader in various university organizations. She is deeply passionate about empowering minorities through higher education and stimulating technology development and science and engineering education in the developing world.
