AC Performance of Nanoelectronics

Peter Burke
University of California Irvine
Department of Electrical Engineering and Computer ScienceIn this talk I will present an overview of the high-frequency properties and applications of carbon nanotubes, one realization of nano-electronic devices, and where the challenges and opportunities lie in this new field. The study of the ac properties of nano-electronic systems is still in its infancy.
The first step towards understanding the high-frequency electronic properties of carbon nanotubes is to understand the passive, ac impedance of a 1d quantum system. We have recently proposed an effective circuit model, currently being tested in our lab, for the ac impedance of a capacitively contacted nanotube, and a dc contacted nanotube . We also recently demonstrated the operation of carbon nanotube transistors at microwave frequencies (2.6 GHz). In our lab, we have also been able to synthesize the world's longest electrically contacted nanotubes (up to 0.4 cm in length), allowing us to elucidate the relationship between contact resistance and bulk resistance. Finally, we recently developed a model for nanotubes as antennas , which could be useful in connecting nano-electronics systems to the outside world via a wireless communications link, thus completely eliminating the need for lithographically defined contacts.Peter Burke received his PhD in physics from Yale University in 1998. From 1998-2001, he was a Fairchild Postdoctoral Scholar in physics at Caltech. He has been with the University of California Irvine in the Department of Electrical Engineering and Computer Science since 2001. His current research areas include high-frequency properties of carbon nanotubes, and the nano-bio interface from an electronics point of view.Date: Wednesday, November 10, 2004
