Opis:: Conducting reticulate doped polymeric films containing BEDT-TTF iodide crystalline networks have been annealed in order to transform the crystallites into crystal phases with metallic conductivity. The microwave conductivity of these films was measured before and after annealing. The temperature dependence of the conductivity changes dramatically with optimal annealing temperatures and times. This change in the behavior corresponds to the transformation of the α-phase into the superconducting α$\text{}_{t}$-phase observed in (BEDT-TTF)$\text{}_{2}$I$\text{}_{3}$ single crystals.

Opis:: Conducting reticulate doped polymeric films containing BEDT-TTF iodide crystalline network were annealed in order to transform the crystallites into crystal phases with metallic conductivity. Measured optical absorption spectra show that annealing shifts the absorption band to higher frequencies and increases the transparency of the films. This behavior corresponds to the transformation of the α-phase into the superconducting α$\text{}_{t}$-phase observed in (BEDT-TTF)$\text{}_{2}$I$\text{}_{3}$ single crystals.

Opis:: The temperature dependence of the electrical properties of heterojunctions with silicon formed by conductive organic polymer composites with networks of two complex tetracyanoquinodimethane salts (of N-n-butyl-isoquinolinium and of diethyl methyl sulphonium cations) were studied. We show that it is possible to prepare junctions with quite good rectifying properties, comparable to those obtained using other organic semiconductors. The observed forward-bias current-voltage characteristics can be satisfactorily fitted using the modified Schottky equation. Reverse bias and C-V characteristics show that the transport mechanism, especially in the case of p-Si junctions is more complicated and probably tunnelling between localized levels plays an important role.

Opis:: Electrical properties of conducting reticulate doped polymeric films containing BEDT-TTF iodide crystalline network were investigated. Conditions of preparation of this kind of films i.e. time of doping by iodine vapours and time and temperature of annealing and their influence on transformation of the BEDT-TTF iodide crystallites into superconducting phase are discussed.
