The cover image shows the atomic structure, optical photograph, and electron diffraction pattern of the novel material, fluorographene. Fluorographene is a two-dimensional crystal and can be considered a stoichiometric chemical derivative of graphene, produced by attaching a fluorine atom to each of the carbon atoms. It is one of the thinnest possible, high-quality insulators with an energy gap of 3 eV. Fluorographene inherits the mechanical strength of graphene, exhibiting a Young's modulus of 100 N m−1 and sustaining strains of 15%. It is chemically inert and thermally stable up to 400 °C even under ambient conditions. These characteristics rival those of Teflon and allow for a wide range of applications.
