Registration : Open to All
Abstract:
Unconstrained graphene is a two-dimensional hexagonal monolayer of carbon atoms. Its unique electronic, structural, physical, chemical and material properties have generated significant interest. The modern era of graphene "gold-rush" started around 2004-2005, when it became possible to fabricate samples using a simple method involving Scotch tape. Since then, the publication trends in this area have been nearly exponential – with more than 10,000 publications in the past seven years with over 3000 publications in just 2010! Last year's Nobel Prize was also awarded for this perfectly two-dimensional material. In this talk, I will review the historical development of this interesting area and discuss the unique properties of graphene and its various nanostructures including bilayer graphene and nanoribbons. Furthermore, I will highlight the modulation of electronic structure and bandgap by applying an electric‐field in various nanostructures. An interesting low power transistor will be proposed on the basis of the electric-field modulation. Further device applications for tunable light emission, energy-harvesting, sensors and electronics will be discussed as well.
About the Speaker:
Hassan Raza is an Assistant Professor in Electrical and Computer Engineering at the University of Iowa since May 2009. For two years, he was a postdoctoral associate at Cornell University. He received his PhD May 2007 and MS Dec 2002 from Purdue University; and BS July 2001 from the University of
Engineering and Technology Lahore Pakistan. He has received "Magoon Award for Excellence in Teaching" from Purdue University. He is also the recipient of "Presidential Faculty Fellowship" and "Old Gold Fellowship" from the University of Iowa. In 2009, his research was chosen as the Annual Highlights among 35 papers by JPCM of IOP. His research group is focused on "anything that is small" for low-power post-CMOS transistor, spintronics and solid-state energy harvesting applications from theoretical, experimental and computational approaches using graphene, molecule, silicon, novel dielectrics and carbon nanotube material systems. He has also served as the editor of a 650 pages book on Graphene Nanoelectronics to be published by Springer in 2012. |
