1. Transistor Paint: Stable Copolymer Thin-Films Sol M. Gruner, Cornell Univeristy, DMR 0936384 CHE-0415369/DMR-304508 Intellectual Merit: These collaborators discovered a new polymeric material showing excellent field effect transistor (FET) performance. These novel copolymers– or paints, as they refer to them – have considerable potential in printable electronics as they have high charge carrier mobilities, excellent air stability, good solution-processibility, and no requirement for post-deposition thermal annealing, all of which are requirements for flexible electronics applications. In addition to excellent electron mobilities, these devices exhibit stable performance in air, showing no significant degradation over 60 days.
