- *Abstract
-
Electronic devices based on organic thin-film transistors (OTFTs) provide several advantages over traditional inorganic-based transistors. OTFT devices are lightweight, flexible and can be easily fabricated into large-area displays. However, the continued development of OTFTs hinges on high-performance gate dielectric materials. Such a material should be insulating, flexible, easily deposited from solution and be compatible with various organic and inorganic semiconductors. The Marks group from Northwestern University has developed a polymer dielectric material that accomplishes these goals. Their innovative gate dielectric material is composed of readily available polymers combined with organosilane crosslinking agents. The addition of a crosslinking agent makes this type of dielectric material impervious to cracking and delamination when the substrate is bent or treated with a solvent. Furthermore, these favorable mechanical properties also allow for the OTFT to be processed after the dielectric is deposited via solution-phase fabrication techniques.
