The experimental study of modified graphene samples by THz time-domain spectroscopy. a Transmission spectra of layered graphene in different modifications (SLG, single layer graphene, FLG few layer graphene, MLG multilayer graphene, i-FLG and i-MLG FeCl3 intercalated) on Kapton polyimide substrate. b The transmission as a function of graphene layer amount for 0.5 and 0.7 THz frequencies on Kapton and glass substrates. c Transmission of layered graphene relative to different substrates
