Abstract
Conference Title: 2013 IEEE 13th International Conference on Nanotechnology (IEEE-NANO) Conference Start Date: 2013, Aug. 5 Conference End Date: 2013, Aug. 8 Conference Location: Beijing, China We demonstrate a buried contact based novel test structure for direct contact resistivity measurement of graphene-metal interfaces. We also observe excellent contact resistivity [integral]1 µO-cm2 without any additional surface modification suggesting that the intrinsic Au-graphene contact is sufficient for achieving devices with low contact resistance. The chemical mechanical polishing less test structure and data described herein highlights an ideal methodology for systematic screening and engineering of graphene-metal contact resistivity to enable low power high speed carbon electronics.
