A mutual rotation of graphene layers can result in various stacking configurations that are not common in natural graphite. The cover image shows a structure, where two layers are relatively rotated by an angle of 2.65°. The interface between the honeycomb lattices produces a Moiré pattern with a unit cell depicted by the rhombus. The layer twisting causes the formation of the AA (red‐colored) and AB (blue‐colored) stacking regions characterized by different electron density localization. On page 270, Lyubov G. Bulusheva, Olga V. Sedelnikova, and Alexander V. Okotrub analyze changes in the optical properties of few‐layer graphenes depending on the stacking geometry and number of layers.
