Highly Crystalline C8-BTBT Thin-Film Transistors by Lateral Homo-Epitaxial Growth on Printed Templates

The latest generation of organic semiconductors display excellent characteristics, with charge mobilities surpassing those of amorphous silicon thin film transistors (TFTs) that are commonly used in today’s flat panel displays. The integration of organic TFTs (OTFTs) into real applications requires high performance and low spread of the electrical characteristics. As transport properties are greatly influenced by the microstructure of the organic layer, single crystalline films offer the greatest potential for high-performance OTFTs.
