| Abstract(in English) | Photo-induced terahertz (THz) transmission modulation through Si substrate coated with thin layer of copper phthalocyanine (CuPc) was investigated using THz time-domain spectroscopy. The charge carrier transfer from Si to CuPc is crucial for photo-induced metallization, which is responsible for the effective THz transmission modulation. We have experimentally verified that the thickness of the CuPc layer is a critical parameter for achieving high charge carrier density for metallization. Transmission through a split-ring resonator array metamaterial, fabricated on CuPc-coated Si utilizing super-fine inkjet printer, can be efficiently modulated by laser light irradiation. Our findings may open the way for various types of metamaterials using organic conjugated materials that are suitable for easy device fabrication using printing technologies. |
