The complex permittivity of PEDOT:PSS
The Journal of Chemical Physics, 2023High permittivity materials are required for efficient organic photovoltaic devices, and the addition of the conjugated polymer composite poly(3,4-ethylenedioxythiophen) polystyrene sulfonate (PEDOT:PSS) to dielectric polymers has been shown to significantly heighten their permittivity.

The permittivity of a suspension treated as a system of hard spheres is calculated in the Born approximation. The structure of the suspension is described by the Percus-Yevick correlation function. The permittivity of the system under consideration is expressed through a nonlocal susceptibility whose spatial extension is determined by the form factor ...

2023 URSI International Symposium on Electromagnetic Theory (EMTS), 2023
The paper is about the interpretation and separability of the effective permittivity in case that both the permittivity and the conductivity are dispersive and thus complex-valued. It is shown that: a) it is always possible to retrieve the static conductivity and the high-frequency (optical) permittivity from the effective permittivity; b) it is in ...
