OPTIMIZATION OF ORGANIC THIN-FILM TRANSISTORS FOR PLASTIC ELECTRONICS: TOWARDS TRANSPARENT COMPONENTS IN NEW DEVICES

Objective

Transparent electronics is an emerging new technology which utilizes “invisible” electronic and optoelectronics circuits. To obtain these circuits, the transistor building blocks materials: semiconductor, gate dielectric and conductor must be optically transparent, raising a true grand challenge. The great problem is that conventional organic semiconductors strongly absorb in the visible and few exhibit acceptable TFT performance when processed from solution. This makes clear that there are great opportunities to develop high-performance materials for the fabrication of optically transparent, mechanically flexible optoelectronics. The main goals of this project are: - Develop high-performance, solution-processable, optically transparent organic semiconductor and dielectric materials. - Establish/implement solution deposition/printing processes to achieve multilayers materials deposition with high resolution. - Enable fully transparent, flexible, solution-processed organic TFTs and circuits. - Enable transparent displays. - Analyze the key parameters determining the TFT response. To achieve these tasks, we will carry out these technical goals: - Synthesize and/or optimise new high band-gap molecular and polymeric semiconductors based on rylene, oligothiophene and dicyanomethylene-containing cores. - Functionalize high-purity single-wall carbon nanotubes (SWCNTs) with semiconducting surfactants. - Optimize formulations for solution deposition, focusing on spin-coating and ink-jet printing. - Optimization of layer-by-layer self-assembled nanodielectrics (SANDs) to enhance transparency. - Print crosslinked polymeric dielectric materials on optically transparent substrates. - Evaluate materials performance in various TFT structures on glass substrates. - Characterize spectroscopically and quantum-chemically semiconductors and gate dielectrics. In my work programme, partial objectives can also constitute research items themselves, opening new
