Abstract
The complex conductivity of CVD-grown graphene films between 0.1 and 1.6 THz are obtained using a non-destructive THz etalon transmittance technique. Critical parameters such as ionized-impurity scattering width and chemical potential are derived. The technique can be extended to extract the complex ac conductivity parameters of other thin conducting films or 2DEG materials with high sheet conductance.
