Stable dielectric response of low-loss aromatic polythiourea thin films on Pt/SiO2 substrate

Stable dielectric response of low-loss aromatic polythiourea thin films on Pt/SiO2 substrate

We have investigated dielectric properties of aromatic polythiourea (ArPTU, a polar polymer containing high dipolar moments with very low defect levels) thin films that were developed on Pt/SiO2 substrate. The detected response is compared to the response of commercially available polymers, such as...
