In article number 2001268, Paolo Samorì and co‐workers report the fabrication of all‐semiconducting mixed‐dimensional van der Waals heterostructures based on monolayer 2D MoS 2 and bottom‐up synthesized 1D graphene nanoribbons, which efficiently suppress the typical persistent photoconductivity effect of MoS 2 . Upon interfacing with physisorbed photochromic molecules, the charge transport of MoS 2 –graphene nanoribbons in field‐effect transistors can be significantly photomodulated, which corresponds to multilevel output currents for high‐performance optoelectronics.
