                                 ABSTRACT
It is now well recognized that energy dissipation in microchips may
ultimately restrict scaling - the downsizing of physical dimensions that has
fuelled the fantastic growth of microchip industry so far. However, energy
dissipation in electronic devices has even bigger consequences. As the use
of transistors increases exponentially in our every day life, electronic
devices are contributing an ever more increasing share to our total energy
consumption (currently 3~4% of US energy consumption), thus becoming
increasingly important for restricting total energy needs and environmental
issues like global warming. In this presentation, I shall talk about a few
electronic and spintronic devices that may reduce dissipation by orders of
magnitude compared to what is believed to be the conventional limit. The
devices that we use today operate very close to equilibrium. I shall show
that if we can drive systems far from equilibrium, it is possible to design
devices that are fundamentally different and, in principle, realize
applications that were considered impossible using conventional devices.


Bio:
Sayeef Salahuddin has recently joined the faculty of Electrical Engineering
and Computer Science at University of California, Berkeley as an assistant
Professor, after completing his PhD in Electrical and Computer Engineering
from Purdue University. He received his B.Sc. in Electrical and Electronic
Engineering from BUET (Bangladesh University of Engineering and Technology)
in 2003 with the Kintarul Islam Gold Medal. His research interests are in
the novel electronic and spintronic devices for low power logic and memory
applications. He pioneered the concept of using 'interacting systems' for
switching, showing fundamental advantage of such systems over the
conventional devices in terms of power dissipation. Sayeef has worked at the
IBM Almaden Research Center as a research intern during summer 2007 and was
the recipient of IBM PhD Fellowship 2007-8 and a Meissner fellowship at
Purdue University in 2003. He also received a MARCO/FCRP Inventor
Recognition Award in 2007.
