共接触石墨烯场效应晶体管的传输特性

Transfer Characteristics in Graphene Field-Effect Transistors with Co Contacts

Ryo Nouchi, Masashi Shiraishi, Yoshishige Suzuki

摘要:

石墨烯场效应晶体管与Co接触作为源极和漏极显示出异常扭曲的传输特性。该异常仅出现在短沟道器件(短于约3微米)中,并且源于接触诱导效应。带变更的石墨烯通道的接触进行了讨论,作为一个可能的机制观察到的异常特性。

英文摘要:

Graphene field-effect transistors with Co contacts as source and drain electrodes show anomalous distorted transfer characteristics. The anomaly appears only in short-channel devices (shorter than approximately 3 micrometers) and originates from a contact-induced effect. Band alteration of a graphene channel by the contacts is discussed as a possible mechanism for the anomalous characteristics observed.
