WebLian-Mao Peng Field-effect transistors (FETs) are fabricated on a large scale and with a high yield of over 95% based on aligned carbon nanotube arrays directly grown on quartz, and exhibit... 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.
