High fmax graphene FET for RF applications(1)
2014中国国际石墨烯创新大会(Grap-China 2014)——Graphene field effect transistor (GFET) has attracted significant attention for potential radio-frequency(RF) applications due to its outstanding carrier mobility and high carrier saturation velocity.Here, we report an improved self-aligned GFET fabrication process and the as prepared devices show good gate coupling and less parasitics, thus good dc and RF performances. The 100 nm gate-length graphene transistor exhibits a record fmax of 105 GHz. Our study shows a pathway to fabrication of high-performance graphene transistors for future application in RF circuits.
