High-Performance Low-Cost Organic Field-Effect Transistors with Chemically Modified Bottom Electrodes

摘要

Organic field-effect transistors (OFETs) have been widely studied due to their potential application in integrated circuits for large-area,flexible,and ultralow-cost electronics.Most research works in this area in the past decade have primarily focused on improving the intrinsic electrical properties of the organic semiconductors and on developing the device fabrication techniques.Electrode materials have not attracted sufficient interest,despite their critical roles in OFETs.The electrodes have to be energetically compatible with the organic semiconductors to form an ohmic contact for efficient charge injection,while they must be chemically stable to the semiconductors and gate dielectrics to prevent adverse chemical interactions at the interfaces.
