SYSTEMATIC STUDY OF THE (ET)(2)I-3 RETICULATE DOPED POLYCARBONATE FILM - STRUCTURE, ESR, TRANSPORT-PROPERTIES AND SUPERCONDUCTIVITY

The crystalline network structure of conducting (ET)(2)I-3 reticulate doped polycarbonate carbonate (RDP) films were analysed by X-ray as we ll as ESR, transport properties and superconducting characteristics of the films were investigated. It was found that under certain conditio ns of the second step of the RDP-film preparation, an oriented alpha-( ET)(2)I-3 crystalline network is formed. The c-axis of the linked alph a-(ET)(2)I-3 crystallites are perpendicular to the film surface and co nsequently their conducting layers are parallel to this surface. Moreo ver, this type of crystalline network orientation is kept during the a lpha--->beta(t)-(ET)(2)I-3 transition which takes place under film ann ealing. Thus, the conducting layers of the linked superconducting beta (t)-(ET)(2)I-3 crystals are also parallel to the film surface. It was demonstrated that superconducting properties are present in all parts of the beta(t)-(ET)(2)I-3 RDP film.
