Abstract

Transmission terahertz time-domain spectroscopy (THz-TDS) measurements of chemical vapor deposition (CVD) graphene on quartz are presented. A mono-layer of graphene has been prepared and measured using THz-TDS. Experimental results were obtained from 100 GHz to 2.5 THz, and the quartz substrate has been initially characterized by extracting the complex permittivity. Graphene has been treated as boundary condition with finite surface conductivity, which has also been calculated. Drude model provide a good fit to the measured surface conductivity, within the frequency range.
