Plasma‐Driven Tuning of Dielectric Permittivity in Graphene (Small 27/2024)

Graphene Sheets This cover art depicts the plasma synthesis of graphene sheets and the in‐situ incorporation of nitrogen atoms into a graphene scaffold to control its dielectric permittivity. Subunitary and even negative dielectric constant values have been achieved in the microwave frequency range....

Summary:Graphene Sheets This cover art depicts the plasma synthesis of graphene sheets and the in‐situ incorporation of nitrogen atoms into a graphene scaffold to control its dielectric permittivity. Subunitary and even negative dielectric constant values have been achieved in the microwave frequency range. This plasma‐driven design of 2D materials at the atomic scale reveals new avenues for controlling electromagnetic waves behaviour.
