Graphite is a crystalline allotrope of carbon characterized by a layered structure in which carbon atoms are arranged in hexagonal sheets of sp²-hybridized networks, with strong covalent bonds within layers and weak van der Waals forces between them. This anisotropic bonding yields high electrical and thermal conductivity parallel to the layers, lubricity, and cleavage along basal planes. In research contexts, graphite serves as a precursor and reference material for studying two-dimensional materials such as graphene, intercalation compounds, and electrochemical behavior in batteries, and is widely used as an electrode material, neutron moderator, and model system for investigating electronic band structure and defect-mediated properties in carbon-based solids.
It has almost been 20 years since the establishment of the field of two-dimensional (2D) materials with the discovery of unique properties of graphene, a single, atomically thin layer of graphite. The significance of graphene ...
Ever since the discovery of the two-dimensional form of graphite (called graphene) almost twenty years ago, interest in 2D materials and their special physical properties has skyrocketed. Famously, graphene was produced by ...
