石墨烯FET中的DOS限制接触电阻

DOS-limited contact resistance in graphene FETs

Kosuke Nagashio, Akira Toriumi

摘要:

石墨烯作为未来高速晶体管材料的候选者之一,由于其超过10,000 cm 2 V-1 s-1的高载流子迁移率而引起了人们的广泛关注。到目前为止,我们一直专注于作为性能杀手的接触特性,因为石墨烯中非常小的态密度可能会抑制从金属到石墨烯的电流注入。本文系统地综述了金属/石墨烯接触特性,并讨论了比接触电阻率的现状和未来需求。

英文摘要:

Graphene has attracted much attention as one of promising candidates of future high-speed transistor materials because of its high carrier mobility of more than 10,000 cm2 V-1 s-1. Up to this point, we have focused on the contact properties as performance killers, as a very small density of states in graphene might suppress the current injection from metal to graphene. This paper systematically reviews the metal/graphene contact properties and discusses the present status and future requirements of the specific contact resistivity.
