Performance enhancement in TIPS-pentacene:PS blend organic field effect transistors by solvent vapor annealing
TL;DR: In this article, the authors used solvent vapor annealing (SVA) to further ameliorate the degree of crystalline order in the active layer of an organic field effect transistors.
Abstract: Organic field effect transistors (OFETs) have been widely explored for their popular applications in flat panel displays and various kinds of affordable sensors. The overall performance of the device depends on the quality of semiconductor-dielectric interface, and degree of crystalline order in the active layer, close to the above said interface. In the special league of solution processed OFETs, semicondutor: polymer blends have been reported as one of the best possible ways to achieve an intimate, uniform and defect free semiconductor-dielectric interface in a single step. In addition, degree of crystalline order can be further ameliorated through solvent vapor annealing (SVA), which essentially controls the evaporation time of the solvent.
