| Outline of Final Research Achievements |
The electromagnetic response of conducting nanosheet thin films in the THz region was investigated in order to pursue its applicability to novel THz optical devices. The transmittance in the THz region of four types of conductive nanosheets (K-RuO2, Na-RuO2, K-IrO2, reduced graphene oxide) was measured and the sheet impedance was calculated. The results showed that K-RuO2 is a material having a relatively high conductivity in the THz region. Owing to the relatively high THz wave adsorption capability of K-RuO2 nanosheet film, it is proposed that it can be applied as a thin film absorber in the THz region. The possibility of application to metamaterials was also pursued. It is concluded that even K-RuO2 nanosheet with the highest conductivity of the 4 nanosheets studied, does not have sufficient conductivity for application as a material of metamaterial structure.
