IEEEE General Interest Meeting

Thursday, September 13th, 2007
Pizza

Want to learn more about IEEE?  Come to our general interest meeting tomorrow, in the Ruth Merrill Center in Wilson Commons.  (Ruth Merrill center is across from the common market through the glass doors.. where there are a lot of couches and chairs)

We will discuss events that we are planning, and give out information about the benefits of joining your professional organization.

Come for the people, the information or just the pizza!

WHEN: Friday , September 14th.  4pm – 5pm

WHERE: Ruth Merrill Center

Welcome back to school.. eat food and be merry!

Time-Resolved Studies of Electron Transport in Ballistic Nanoconstrictions

CSB 209

Summary

There has long been enormous interest in the electrical properties of small nanostructures, motivated by their potential for use as the basic building blocks of future electrical-circuit technologies. In the ultimate applications of these structures, it will be necessary to excite them with very-high-frequency electrical signals, at least in the microwave range. In spite of this, the vast majority of work on the electrical properties of nanostructured devices to date has focused on their static (DC) behavior. Motivated by this, we have explored the transient microwave conductance of one of the most important nanoelectronic devices, namely the nanoscale constrictions known as quantum point contacts. While the DC properties of these devices are well understand, our transient studies reveal that they can exhibit an unexpectedly-large capacitance that may allow their application as compact capacitors, or as nanoscale circuits that are capable of exhibiting active behavior (high-pass signal filtering). In my talk I will discuss the possible origins of this phenomenon, after first giving a brief overview of activities in nanoelectronics research that are currently ongoing in my group.

Bio

Bird

Jonathan Bird joined the SUNY Buffalo Department of Electrical Engineering as Professor in Fall 2004. Prior to this, he obtained his B.Sc. (First-Class Honors) and Ph.D. degrees in Physics from the University of Sussex (United Kingdom), in 1986 and 1990, respectively. He was a JSPS visiting fellow at the University of Tsukuba (Japan) from 1991 – 1992, after which he joined the Frontier Research Program of the Institute of Physical and Chemical Research (RIKEN, also in Japan). In 1997, he was appointed as Associate Professor in the Department of Electrical Engineering at Arizona State University, where he served until joining UB. Prof. Bird’s research is in the area of nanoelectronics. He is the co-author of more than a hundred peer-reviewed publications as well as of an undergraduate textbook.
