Contactless graphene conductivity mapping on a wide range of substrates with terahertz time-domain reflection spectroscopy
We demonstrate how terahertz time-domain spectroscopy (THz-TDS) operating in reflection geometry can be used for quantitative conductivity mapping of large area chemical vapour deposited graphene films on sapphire, silicon dioxide/silicon and germanium. We validate the technique against measurements...
