SEMINAR: Scaling and Printing Electronics Using Nanomaterials
September 13, 2019 @ 10:00 am - 11:00 am
Silicon-based electronics remain the backbone of the ongoing digital revolution and continue to enhance computational ability, as well as the accessibility of data. As the range of possible applications for electronics grows, so does the realization that there are distinct limits to what silicon can do. Meanwhile, nanomaterials have been studied for decades for their attractive electronic properties coupled with mechanical flexibility, thermal resilience, and compatibility with solution-phase processing. From 1D carbon nanotubes (CNTs) to 2D graphene and transition metal dichalcogenides (TMDs), there is a growing list of nanomaterial options. Making use of the unique attributes offered by nanomaterials opens the way for new types of electronics that add value far beyond Moore’s law-related improvements. In this talk, two distinct applications employing nanomaterials will be discussed: scalable low-voltage transistors and printed electronic systems. Each of these applications relies on capabilities that are unique to nanomaterials, which leads to performance, fabrication, and/or function that are not possible with traditional semiconductors. For instance, the low-cost printing of electronic circuits and sensors that must operate in harsh environments will be demonstrated. Additionally, 2D transistors that are scalable in terms of both voltage (negative capacitance devices) and size (pure edge contacts) will be discussed. The primary takeaway of this talk should be an overview of a new era of electronics that is uniquely possible using nanomaterials.
Dr. Aaron Franklin received his Ph.D. in Electrical Engineering from Purdue University in 2008 and then spent six years on the research staff at the IBM T. J. Watson Research Center in Yorktown Heights, NY. In 2014, he joined the faculty at Duke University where his research group explores the use of nanomaterials for nanoscale devices, printed electronics, and sensors for Internet-of-Things (IoT) applications. Sponsored research in the Franklin lab includes projects involving high-performance transistors, printed sensors for IoT, thin-film transistors, and biomedical electronic devices. In addition to research and academic accomplishments, Dr. Franklin is experienced in technology translation, holding more than 50 patents and successfully founding a funded company (Tyrata, Inc.) based on technology from his lab – printed electronic sensors for measuring tread wear on vehicle tires.
