Theory of Nano-Electron-Fluidic Logic (NFL): A Digital "Electronics" Concept

Speaker : Dr. Héctor J. De Los Santos


As predicted by Gordon Moore more than 40 years ago, the number of transistors able to fit on a computer chip has doubled approximately every 18 months. But if the trend is to continue for the years to come, it will have to be with technology other than the conventional CMOS design. As the size of transistors gets down to the nanoscale, CMOS devices begin to suffer from several issues, in particular, increased resistance, decreased channel mobility, and increased manufacturing costs. To overcome the challenges involved with scaling, researchers from around the world have begun to look for alternatives to CMOS technology. Our recently introduced concept, called nano-electron-fluidic logic (NFL), is based, not on electron particle transport, but on the generation, propagation, and manipulation of surface plasma waves (plasmons) in an electron fluid. NFL gates are projected to exhibit femtojoule power dissipations and femtosecond switching speeds at finite temperatures, while taking full advantage of established semiconductor manufacturing infrastructure. NFL represents a paradigm shift in digital technology, and is poised as a strong candidate for “beyond-CMOS” digital logic. This talk presents the theory, physics and design principles of NFL.  

About the speaker:

Héctor J. De Los Santos received the Ph.D. degree in electrical engineering from Purdue University, West Lafayette, IN, in 1989. He founded NanoMEMS Research, LLC, Irvine, CA, a company engaged in Nanoelectromechanical Quantum Circuits and Systems (NEMX) and RF MEMS (NanoMEMS) research, consulting, and education, where he focuses on discovering fundamentally new devices, circuits and design techniques. Prior to founding NanoMEMS in 2002, he spent two years as a Principal Scientist, RF MEMS, at Coventor, Inc., Irvine, CA. From 1989 to 2000, he was with Hughes Space and Communications Company, Los Angeles, CA, where he served as Principal Investigator and the Director of the Future Enabling Technologies IR&D Program. Under this program he pursued research in RF MEMS, quantum functional devices and circuits and photonic bandgap crystal devices and circuits. He holds over 30 U.S., European, German and Japanese patents and is author of bestseller textbooks, including, Introduction to Microelectromechanical (MEM) Microwave Systems,Norwood, MA: Artech House, 1999 [This book was the first in the RF MEMS field and has become an Artech House classic, now being in their IPF® (In-Print-Forever®) program], RF MEMS Circuit Design for Wireless Communications, Norwood, MA: Artech House, 2001, and Principles and Applications of NanoMEMS Physics, Dordrecht: The Netherlands: Springer, 2005. His most recent book, Radio Systems Engineering: A Tutorial Approach, was published by Springer, New York, in 2014. His research interests include, theory, modeling, simulation, design and demonstration of emerging devices (electronic, plasmonic, nanophotonic, mechanical systems in the quantum regime, etc.), and wireless communications.

During the 2010-11 academic year he held a German Research Foundation (DFG) Mercator Visiting Professorship at Institute for High-Frequency Engineering and Electronics, Karlsruhe Institute of Technology/University of Karlsruhe,Germany, where his activities included teaching, and conducting research on his DFG-funded project "Nanoelectromechanical Interferometric Tuning with Non-Equilibrium Cooling for Microwave and mm-Wave Electronics". From 2001-2003 he lectured worldwide as an IEEE Distinguished Lecturer of the Microwave Theory and Techniques Society. Since 2006 he has been an IEEE Distinguished Lecturer of the Electron Devices Society. He is a member of Tau Beta Pi, Eta Kappa Nu and Sigma Xi. He is an IEEE Fellow.
