Organic semiconductors have been widely studied in recent years because of their light-weight, flexibility, and low-end. Soluble materials have been developed to further minimize process costs; among these 6,13-bis(triisopropylsilylethinyl) pentacene (TIPS-pentacene) combines printability, air-stability, and high electrical performances. TIPS-pentacene crystals yielded by simple drop-casting are affected by random orientation, lack of areal coverage, and non-homogeneous film thickness, which lead to poor electrical performances and high device-to-device variability. To reduce morphological issues and therefore increase Organic Field-Effect Transistors (OFETs) performances, in this research, organic films have been yielded by applying two methods; a thermal gradient and blending TIPS-pentacene with a polymeric material (polystyrene).
