Event Type: 


Electrical engineering is at a crossroads. For the last fifty years, semiconductors have been driving the development of information technology, which has completely transformed our society. Conventional electronics, however, is reaching scaling and performance limits which jeopardizes future developments. New materials with unique properties are necessary and graphene, a one atom thick layer of sp2 bonded carbon, is at the top of potential candidates.

Graphene not only has outstanding transport properties, but it also shows many unique properties not found in any other high performance electronic material. It is flexible, transparent, ultimately scalable, easily transferable to any surface, and its ambipolar conduction offers new possibilities for advanced electronics. 

In this talk, we describe how the use of these properties allows the development of new devices, which can overcome some of the main limitations of traditional electronics in terms of sensitivity, maximum frequency, and linearity. Several novel devices will be discussed for RF communications and remote sensing, including graphene frequency multipliers, graphene RF mixers and graphene chemical sensors.


Speaker's bio:

Prof. Palacios studied Telecommunication Engineering at the Universidad Politécnica de Madrid and received his PhD from the University of California – Santa Barbara in 2006. Since that year, he leads the Advanced Semiconductor Materials and Devices Group at the Massachusetts Institute of Technology. His research focuses on the development of new electronic devices based on the combination of new materials (GaN and graphene) and nanotechnologies.

Prof. Palacios’ work has been recognized with several awards including the 2011 Presidential Early Career Award for Scientists and Engineers (PECASE), the 2010 Young Scientist Award of the International Symposium on Compound Semiconductors (ISCS), the 2009 ONR Young Investigator Award, the 2009 NSF CAREER Award, the 2008 DARPA Young Faculty Award, as well as multiple best papers awards. He has authored more than 200 contributions on advanced semiconductor devices in international journals and conferences, 40 of them invited, and several book chapters and patents. 

Since 2006, Prof. Palacios has been leading the development of new applications for graphene-based materials. In 2010, he founded the MIT Center for Graphene Devices and Systems, with the goal to coordinate the graphene work at MIT. He is also the co-founder of the IEEE MTT Nanotechnology Committee and the MTT Distinguished Microwave Lecturer on graphene nanotechnology.
