Quantitative mapping of large area graphene conductance
Paper in proceeding, 2012
We present quantitative mapping of large area graphene conductance by terahertz time-domain spectroscopy and micro four point probe. We observe a clear correlation between the techniques and identify the observed systematic differences to be directly related to imperfections of the graphene sheet on the length scale of several micrometers.
