This cover illustrates the incorporation of a thin Al2O3 barrier layer for resolving current limitations of electrically tunable graphene–metal hybrid metasurfaces (article 2303085 by Fei Han, Xuezhi Zheng, Ewald Janssens, and co-workers). The authors' device improves the electronic doping ability of graphene, thereby enhancing the tuning range of mid-infrared metasurfaces. The straightforward approach is not only promising for future compact tunable optical devices, but it also provides guidelines for engineering future 2D material-based optoelectronics.
