ResumoAbstract We report results on the fabrication of thin films of the organic radical cation salt (BEDO-TTF)2.4I3. The title compound is an organic metal with a room temperature dc-conductivity of 180 – 360 S/cm. On amorphous substrates as quartz glass and silicon wafers ( Si SiO 2 ), we found one or more orientations of the crystalline material with respect to the substrate plane. On NaCl there is only a single, very strong Bragg reflection, which is due to the very good, substrate-induced orientation of the film. Scanning electron microscopy reveals growth of grains on the quartz glass substrates, whereas on NaCl large smooth areas with 1 to 10 μm edge size are observed. The dc-conductivity shows a slightly activated behaviour with an activation energy of 20 meV and a room temperature value of 1 S/cm.
