Graphite to graphene
WebJan 28, 2024 · Several graphite samples (see “Materials and methods”) were irradiated in a clean, vacuum chamber. The working pressure of the chamber is 2 × 10 –3 –7 × 10 –4 Pa (0.7 × 10 –8 –2 ... WebA layer of graphite is called graphene. Graphene is produced through layers of graphite compound exfoliated layer by layer until what remains is a ‘honeycomb’ carbon sheet. In layman’s terms, a stack of graphene is graphite. The discovery of graphene started long before the extraction and characterization of graphene (Novoselov et al. 2004).
