High Frequency Solution-processed Organic Field-effect Transistors With High-resolution Printed Short Channels

Our colleagues from XTPL, Mateusz Łysień and Łukasz Witczak, collaborated with Tommaso Losi, Pietro Rossi, Paola Moretti, Chiara Bertarelli, Mario Caironi from Istituto Italiano di Tecnologia and Virgilio Mattoli from Centre for Material Interfaces to publish a paper titled "High frequency solution-processed organic field-effect transistors with high-resolution printed short channels". The paper has garnered positive feedback since its publication.

Using the Ultra-Precision Deposition method, the paper investigates the use of high-resolution, direct-written metallic contacts for developing fully-solution fabricated organic transistors. The results showed that an average transition frequency of 25.5 MHz at 25 V was achieved, which is the highest frequency achieved with OFETs where critical features are defined by a printing method.

Thank you for this interesting article and publication! The article shows the increasig improvements in printing active elements in such diameters never seen before. I think, we can exept more news and results in this field - congrats and keep going! You can find the Link to the full tech article at ResearchGate.
