Improved electrode structure and innovative organic field-effect transistor have been developed 2

The lower electrode structure can be fabricated using photolithography technology, which facilitates large-scale industrial production and reduces product costs. However, the lower electrode structure device has poor field effect performance due to the larger electrode semiconductor contact resistance.diode  In addition, the widely used source drain electrode material is the high cost gold electrode. From a practical application perspective, it is best to use low-cost metal electrodes such as copper and silver. However, due to their low work function, the performance of field-effect devices prepared using copper or silver as source drain electrodes is not ideal.diode  Therefore, preparing low-cost and high-performance devices with lower electrode structures is an important goal in the research of organic field-effect transistors. In recent years, organic field-effect transistors have attracted widespread attention and made significant progress in academia and industry due to their potential applications in active matrix displays, radio frequency tags, and other fields. At present, the performance of high-performance organic field-effect transistors can be comparable to widely used amorphous silicon transistors. Compared to inorganic field-effect transistor devices, organic field-effect transistors have unique advantages of low cost and flexibility.diode
