A highly flexible and transparent transistor based on an exfoliated MoS 2 channel and CVD‐grown graphene electrodes is reported by W.‐K. Hong, H. C. Ko, and co‐workers on page 3295 . Introducing 2D nanomaterials provides high mechanical flexibility (available bending radius: ± 2.2 mm), optical transmittance (74%), and high current on/off ratio (>10 4 ) with an average field effect mobility of ≈4.7 cm 2 V −1 s −1 , all of which cannot be achieved by other transistors consisting of a MoS 2 active channel/metal electrodes or graphene channel/graphene electrodes. In particular, the MoS 2 /graphene interface has a low Schottky barrier of ≈22 meV, which is comparable to the MoS 2 /metal interface.
