Abstract: An ambipolar dual-channel field-effect transistor (FET) with a WSe2/MoS2 heterostructure formed by separately controlled individual channel layers is demonstrated. The FET shows a switchable ambipolar behavior with independent carrier transport of electrons and holes in the individual layers of MoS2 and WSe2, respectively. Moreover, the photo-response is studied at the heterointerface of the WSe2/MoS2 dual-channel FET © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
