摘要：
High performance short channel OTFTs with field effect mobilities greater than 1cm(2)V(-1)s(-1) have been developed for OLED driver applications incorporating soluble crystalline semiconductor materials. We highlight the impact of contact resistance on the mobility in these devices and show by functionalising both the source and drain contacts and channel regions in a top gate bottom contact device architecture that the mobility can be significantly improved. Our approach also includes the optimisation of solvent selection from which the semiconductor material is deposited in order to enhance crystalline domain formation.
