Study Results from Pohang University of Science and Technology (POSTECH) in the Area of General Science Reported (Template-mediated nano-crystallite networks in semiconducting polymers)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Investigators publish new report on Science. According to news reporting originating from Pohang, South Korea, by VerticalNews correspondents, research stated, "Unlike typical inorganic semiconductors with a crystal structure, the charge dynamics of pi-conjugated polymers (pi-CPs) are severely limited by the presence of amorphous portions between the ordered crystalline regions. Thus, the formation of interconnected pathways along crystallites of pi-CPs is desired to ensure highly efficient charge transport in printable electronics."

Our news editors obtained a quote from the research from the Pohang University of Science and Technology (POSTECH), "Here we report the formation of nano-crystallite networks in pi-CP films by employing novel template-mediated crystallization (TMC) via polaron formation and electrostatic interaction. The lateral and vertical charge transport of TMC-treated films increased by two orders of magnitude compared with pristine pi-CPs. In particular, because of the unprecedented room temperature and solution-processing advantages of our TMC method, we achieve a field-effect mobility of 0.25 cm(2) V-1 s(-1) using a plastic substrate, which corresponds to the highest value reported thus far."

According to the news editors, the research concluded: "Because our findings can be applied to various pi-conjugated semiconductors, our approach is universal and is expected to yield high-performance printable electronics."
