Asif Khan has been chosen for a DARPA Young Faculty Award. Khan is an assistant professor in the Georgia Tech School of Electrical and Computer Engineering (ECE), where he has been on the faculty since 2017.

Khan is receiving this award for his research on ferroelectric field-effect transistors for embedded non-volatile memory applications. Ferroelectric field-effect transistors is one of the most-promising device technologies for artificial intelligence (AI) and machine learning (ML) hardware, due to its energy efficiency and compatibility with high-volume semiconductor manufacturing. The project will focus on solving the critical voltage problem of this device technology, by identifying and implementing new strategies for interface defect reduction in and the downscaling of the ferroelectric gate-dielectric stack. 

Khan works on advanced semiconductor devices that will shape the future of computing in the post-scaling era. His research group currently focuses on ferroelectric devices in all aspects ranging from materials physics, growth, and electron microscopy to device fabrication, all the way to ferroelectric circuits and systems for AI/ML/data-centric applications.

His early career work led to the first experimental proof-of-concept demonstration of a physical phenomenon, namely the negative capacitance, in ferroelectric materials, which can reduce the power dissipation in electronic devices below the “fundamental” thermodynamic limit. Negative capacitance is currently a vibrant research area in materials science, condensed matter physics, and electrical engineering, and it is being pursued by all major semiconductor companies for advanced transistor technologies.

In the past, Khan has received multiple awards, including the NSF CAREER Award (2021), the Intel Rising Star Award (2020), Qualcomm Innovation Fellowship (2012), TSMC Outstanding Student Research Award (2011), and the University Gold Medal from Bangladesh University of Engineering and Technology (2011). He was also named to the Center for Teaching and Learning Class of 1934 CIOS Honor Roll for his outstanding teaching in ECE8863 Quantum Computing Devices and Hardware in Fall 2020.

Khan’s group currently consists of seven graduate students and two research staff members. They publish in flagship microelectronics conferences, such as the International Electron Devices Meeting (IEDM) and the Symposium on VLSI Technology, and in journals including IEEE Electron Device Letters, IEEE Transactions on Electron Devices, Nature Electronics, Nature Materials, and Nano Letters. His students received multiple international and Institute-level awards, including the IEEE EDS Masters Student Fellowship (Prasanna Ravindran, 2020) and the Georgia Tech ECE's Colonel Oscar P. Cleaver Award (Nujhat Tasneem in 2018 and Zheng Wang in 2017) for achieving the highest score on the ECE Ph.D. preliminary examination, which was the criteria for the award up to 2018.

Asif Khan has been named as a recipient of the NSF CAREER Award. He is an assistant professor in the Georgia Tech School of Electrical and Computer Engineering (ECE) and also holds a courtesy appointment in the School of Materials Science and Engineering.

The title of Khan’s award is “Antiferroelectric Negative Capacitance Transistors for Ultra-low Power Computing,” and it will start on March 15, 2021 and end on February 28, 2026. 

Today's society is experiencing an unprecedented growth of its digital footprint – be it in the form of uploading a photo on Facebook, live-streaming a teaching module to a massive global audience on YouTube, or commandeering a revolution via Twitter. This convenience of modern computing, however, comes with a steep cost in terms of energy use and environmental impact. Today, the global information infrastructure, such as data centers, emit as much greenhouse gases as that of the state of Nevada or a country, such as The Netherlands or Malaysia, and constitute around 1 percent of world-wide electricity demand. According to scientific estimates, this fraction may increase to a double digit percentage in the next 15-20 years. 

At the core of this predicament lies the fact that the fundamental building blocks of digital hardware – the transistors – have long been overdue for a prime upgrade in terms of their energy efficiencies. The proposed research aims to explore an energy-efficient transistor concept – known as a negative capacitance field-effect transistor, using a new class of materials called antiferroelectric oxides. 

Khan joined the ECE faculty in 2017. His research is on advanced semiconductor devices—devices that will shape the future of computing in the post-scaling era. His research group currently focuses on ferroelectric devices, in all aspects ranging from materials physics, growth, and electron microscopy to device fabrication, all the way to ferroelectric circuits and systems for artificial intelligence/machine learning/data-centric applications. Khan’s Ph.D. work led to the proof-of-concept demonstration of the negative capacitance phenomenon in ferroelectric materials, which can reduce the power dissipation in electronic devices below the ‘fundamental’ thermodynamic limit. This culminated in the initial development of the field of negative capacitance.

Khan has published 2 book chapters and 70 journal and peer-reviewed conference publications, and he has given 20 invited talks and tutorials at premier microelectronics and ferroelectric conferences. Khan currently has one patent pending at Intel. 

Khan’s awards include the NSF CAREER award (2021), Intel Rising Star Award (2020), Qualcomm Innovation Fellowship (2012), TSMC Outstanding Student Research Award (2011), and the University Gold Medal from Bangladesh University of Engineering and Technology (2011). His group at Georgia Tech consists of six Ph.D. students and three research engineers, many of whom won Institute-level and international awards, including an IEEE Electron Devices Society (EDS) Masters Student Fellowship (2020). Khan’s research is supported by the National Science Foundation, the Defense Advanced Research Projects Agency, the Semiconductor Research Corporation, and Intel Corporation. 

Khan has also developed a graduate course, ECE 8863A Quantum Computing Devices and Hardware, as a part of the campus wide response to the national prioritization of quantum computing, known as the National Quantum Initiative Act (NQIA) that was signed by the U.S. president in 2018. Khan recently received the Class of 1934 CIOS Honor Roll award for excellence in teaching this course in Fall 2020. 

Colin Potts, vice provost for undergraduate education and professor of interactive computing at Georgia Tech, has accepted a position as provost and executive vice chancellor of Academic Affairs at Missouri University of Science and Technology (Missouri S&T). He will be at Tech through late May.

Potts has led Georgia Tech’s Office of Undergraduate Education since 2012, overseeing offices and programs affecting undergraduate education including Serve-Learn-Sustain, the Honors Program, Undergraduate Advising and Transition, Academic Enrichment Programs, Tutoring and Academic Support, Complete College Georgia and Retention, Summer Session Initiatives, the Career Center, and Pre-Graduate and Pre-Professional Advising.
