Findings from Aix-Marseille University Provides New Data about Organic Electronics (Laser-induced forward transfer of polythiophene- based derivatives for fully polymeric thin film transistors)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Investigators publish new report on Organic Electronics. According to news reporting originating in Marseille, France, by VerticalNews journalists, research stated, "Polymeric thin-film transistors (pTFTs) have been fabricated by pulsed-laser printing of semiconductor and conductor polythiophene-based derivatives. Thin solid layers of semiconducting poly(3,3''' didodecylquaterthiophene) (PQT-12) have been transferred by a laser-induced forward transfer (LIFT) technique on Si/SiO2 receiver substrates."

The news reporters obtained a quote from the research from Aix-Marseille University, "Optimization of the transfer conditions and of the pixels morphologies has been realized. A marked improvement in the quality of the pixels has been observed, in terms of morphology and structure, by reducing the environmental pressure to 90 mbar during LIFT. Subsequently, poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS) has also been laser-printed and used as source/drain electrodes in the transistor configuration."

According to the news reporters, the research concluded: "Functional polymeric transistors have been obtained with high field-effect mobility up to 2 x 10 (2) cm(2) V (1) s (1) together with current modulation of 10(4)."
