Charge Injection In Regioregular Poly-(3-hexythiophene) Organic Field-Effect Transistors With Different Metal Electrodes

摘要：

　　Here we report on regioregular poly-(3-hexythiophene) (P3HT) organic field-effect transistors (OFETs) with various metal electrodes: pristine Au, pristine Cr, and Cr/Au.Compared to the performance of OFETs using different electrodes, the OFETs with Au electrode have better mobility (μ =0.0090 cm2/Vs) and larger current at the same source-drain voltage and gate voltage.The enhancement of the device performance with Au electrode can be attributed to a small contact resistance and a small barrier height to P3HT for hole carrier injection.
