Illinois ECE Distinguished Colloquium Series


This talk will present our latest research adventures on 2D nanomaterials towards greater scientific understanding and advanced engineering applications. In particular, the talk will highlight our work on flexible electronics, zero-power devices, single-atom monolayer memory, non-volatile RF/5G/6G switches, and wearable tattoo sensors for mobile health. Non-volatile memory devices based on 2D materials are an application of defects and is a rapidly advancing field with rich physics that can be attributed to metal adsorption into vacancies. The memory devices can be used for neuromorphic computing and operate as switches up to 500GHz. Likewise, from a practical point, electronic sensors and tattoos based on atomic materials such as graphene have ushered a new material platform with highly desirable practical attributes including optical transparency, mechanical imperceptibility, and is the thinnest conductive electrode sensor that can be integrated on skin for physiological measurements including blood pressure monitoring with Class A performance. In addition, the same material can be configured for biosensing with state-of-the-art sensitivity for virus detection. 


Deji Akinwande is an Endowed Chair Professor of Engineering at the University of Texas at Austin, and a Fellow of the IEEE, the MRS, the APS, and the AAS. His research focuses on 2D materials, pioneering device innovations from lab towards applications for which he is a Clarivate Highly Cited Researcher. He received the PhD degree from Stanford University in 2009. Prof. Akinwande has been honored with the 2018 Fulbright Specialist Award, 2017 Bessel-Humboldt Research Award, the U.S Presidential PECASE award, the inaugural Gordon Moore Inventor Fellow award, and several “Early Career Awards” from the IEEE, the NSF, and the DoD. His research achievements have been featured by Nature news, Time and Forbes magazine, BBC, CNN, Discover magazine, Wall Street Journal, and many media outlets. He serves as an Editor ACS Nano and Nature NPJ 2D Materials & Applications, and on the editorial board for Science. He was the co-Chair of the Gordon Research Conference on 2D electronics, and was a past Chair of the 2018/2019 Device Research Conference (DRC), and the Nano-device sub-committee for the 2018 IEEE IEDM Conference. He co-authored a textbook on carbon nanotubes and graphene device physics by Cambridge University Press, and was recently a finalist for the Regents' Outstanding Teaching Award, the highest teaching award from the University of Texas System.
