Abstract :
Carbon-based materials have emerged as next generation electronic materials for device applications. In this work, radio-frequency behavior of square graphene is studied and characterized up to 67GHz. After an elaborate de-embedding process in which four dummy structures and three steps are employed, a new two-port physical-based equivalent circuit model is proposed and verified. It is estimated that square graphene has about 200 times larger inductance than square metal with nearly the same quality factor and thus a graphene ribbon consisting of pieces of square graphene aligning is a promising material for future on chip inductors.
