There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

The MRSEC Seminar 2012 Series welcomes Dr. Eric Vogel a faculty member of the School of Materials Science & Engineering at Georgia Tech, on April 19, 2012 at 3:00pm in the Marcus Nanotechnology Building conference rooms located on the first floor. His talk is title: Issues with Characterizing Transport Properties of Exfoliated and CVD Single Layer Graphene Devices.
Abstract:
The transport properties of exfoliated and CVD single layer devices are typically characterized using a conventional test structure consisting of graphene on silicon dioxide with deposited metal contacts. Two of the primary parameters affective the total resistance of this structure are the channel mobility and contact resistance. A simple model is used to describe the impact of these parameters on total device resistance and experimentally extract them. Important issues related to characterizing the transport properties of these graphene devices are presented. The transport properties of CVD graphene and exfoliated graphene are compared.
