“…For all the LB films prepared from C n + BEDO-TTF mixtures with 1:2 molar ratio, R s increases remarkably in the temperature range of 150−300 K. This means that without the disorder effects below 150 K the sheet resistance would extrapolate to values close to zero as is observed in single crystals of BEDO-TTF-based salts. 24,25 The room temperature resistivity value for single crystals of the polyoxometalatecontaining radical salt of BEDO-TTF is reported as 0.027 Ω•cm and found to gradually decrease with the decreasing temperature, reaching a value of 0.001 Ω•cm at 2 K. 25 For these crystals, the temperature dependence of the resistivity is found to be linear above 200 K and quadratic below 200 K. The value of the resistivity and its thermal variation correlate with the structural properties of the compound as suggested by the previous studies on radical cation salts based on BEDO-TTF. 24−27…”

Conducting Langmuir−Blodgett films are one of the candidates for molecular electronics. We investigated the structural and electrical properties of Langmuir−Blodgett films built up as a mixed molecular system of bis-(ethylenedioxy)tetrathiafulvalene, in short BEDO-TTF, and fatty acid, as a function of (a) the alkyl chain length of the fatty acid and (b) the fatty acid: BEDO-TTF molar ratio in the starting solution from which the Langmuir film is prepared. The Langmuir−Blodgett films deposited from mixtures with molar ratio 1:2 showed better quality in terms of crystallinity and electrical conduction. Moreover, LB films with longer alkyl chain fatty acids were better ordered even at lower molar ratio.

Nevertheless, band structure [5], (e) (TMTSF)2NO3, in the temperature range between the anion ordering and the spin density wave condensation [6] and (f) (BEDO)4Ni(CN)4·4CH3CN [7]. These FS achieve networks of hole-type (pink solid lines) and electron-type (green solid lines) orbits.…”

International audienceEven although organic conductors have complicated crystalline structures with low symmetry and large unit cells, band structure calculations predict a multiband quasi-two-dimensional electronic structure yielding a very simple Fermi surface in most cases. Although few puzzling experimental results have been observed, data for numerous compounds are in agreement with calculations, which make them suitable systems for studying magnetic quantum oscillations in networks of orbits connected by magnetic breakdown. The state of the art of these problematics is reviewed
