Recent progress on rubrene as active layer in organic field-effect transistors

Organic field-effect transistor (OFET) is kind of organic electronic devices, which consists of gate insulator layer, an active layer, and 3 electrodes (source, gate electrodes, and drain). Among them, the active layer as a key part has been widely concerned by scientific researchers. Rubrene, as a member of the star molecules, has been widely studied. Rubrene exhibits attractive properties, for instance, having one of the utmost reported transistor mobilities at room temperature, and the crystal growth mode is different in different solvents and so on. This paper summarized several methods for producing high-performance single-crystal transistors. The objective of this problem is to offer an extensive overview of rubrene as active layer in OFET.
