We theoretically propose a dual-channel current valve based on a three terminal zigzag graphene nanoribbon (ZGNR) junction driven by three asymmetric time-dependent pumping potentials. By means of the Keldysh Green's function method, we show that two asymmetric charge currents can be pumped in the different left-right terminals of the device at a zero bias… CONTINUE READING
