Abstract :
This paper presents a scalable technique to fabricate high performance graphene transistors with self-aligned buried gates process. Graphene FETs with two different structures have been compared and the buried gated structure shows less fringing capacitance and more reliable contacts. The buried-gate graphene transistor shows field-effect mobility of 6,100 cm2/V·s according to the transconductance measurement. This result paves the way for manufacturable high quality graphene transistor technology.
