Latest Patents

The supplied patent information describes “Solution process for fabricating high-performance organic thin-film transistors.” The invention uses a solution or ink containing an organic semiconductor and a mediating polymer, such as polyacrylonitrile or polystyrene, in an organic solvent such as chlorobenzene or dichlorobenzene.

The semiconductor and polymer can be combined at weight ratios ranging from 5:95 to 95:5, with 20:80 to 80:20 identified as preferred. The composition can be deposited by solution coating or printing to form a semiconductor film, which is then dried and, if needed, thermally annealed for use as the OTFT channel.

According to the supplied description, devices made with the mediating polymer can achieve improved field-effect mobility and current on/off ratios compared with devices whose channel semiconductors are fabricated without it.
