Porosity copper layer graphene coating perspective

The illustration depicts a hexagonal lattice or honeycomb structure representing graphene, a single layer of carbon atoms. The atoms are bonded together in a two-dimensional (2D) plane using covalent bonds with sp2 hybridization. The layer is shown in a light blue color against a brown backdrop, structured on top of a brown substrate, possibly silicon oxide or another material. This structure demonstrates properties relevant to fields such as nanomaterials, solid-state physics, chemistry, and electrical engineering, including high electrical conductivity, mechanical strength, and unique optical properties.
