Graphene-based ambipolar rf mixers
WebSeveral novel applications of graphene ambipolar devices have been demonstrated experimentally at a relatively low frequency. Figures 1 and 2 show graphene frequency doublers and graphene ambipolar RF mixers demonstrated at 10s of MHz. Other applications of ambipolar electronics include ambipolar Binary Phase Shift Keying … WebIn this letter, we demonstrate the use of the ambipolar-transport properties of graphene for the fabrication of a new kind of RF mixer device. Due to the symmetrical ambipolar conduction in graphene, graphene-based mixers can effectively suppress odd-order intermodulations and lead to lower spurious emissions in the circuit.
