Journal ArticleDOI
TL;DR: In this paper, small dots of Ag and Au were added upon the organic layer, and the thus formed diodes were characterized by currentvoltage ( j-itV ) and capacitance-voltage( C-V ) measurements.

Journal ArticleDOI
TL;DR: Oligomers of thiophene α-5T and α-6T were synthesized and vacuum evaporated as thin solid films onto platinized glass slides They all behave as p-type semiconductors, and good rectifying barriers were obtained at α-nT/Ag junctions as discussed by the authors.

Journal ArticleDOI
TL;DR: In this paper, composites of electrically conducting poly(bithiophene)-poly(pyrrole) copolymer and hydrophobia poly(vinyl chloride) (PVC), in combination with catalytic dispersion of RuO2, were used to stabilize the semiconductor photoanodes during visible light-induced oxidation of water to oxygen.

TL;DR: In this article, the authors show that the conductivity of the 6T +. salt is weakly temperature dependent, with an activation energy of 32 meV above 100 K and a tendency to level Dff at lower temperatures.
Abstract: Oxidative doping of individual thiophene oligomers nT (n = 3 to 6) with FeC13 in dilute CH 2 Cl 2 solution generates the corresponding radical cations (polarons) nT +. . as evidenced by in-situ visible/near infrared absorption and electron spin resonance spectroscopies. The nT + . species in solution progressively precipitate as conducting (0′300K = 10 −1 −10 −2 S/cm) and strongly paraaagnetic radical cation salts (g = 2.003, ΔH PP ∼ 4–8 G). The conductivity of the 6T +. salt is weakly temperature dependent, with an activation energy of 32 meV above 100 K and a tendency to level Dff at lower temperatures. In the case of the sexithienyl radical 6T +. , further doping results in the quantitative conversion into the dication 6T ++ (bipolaron).
