Artificial graphite is made by extruding or pressing a mixture of pitch and coke, then baking and graphitizing by heating at temperatures from 2000 to 30000 C. The crystal size depends on the starting material and the temperature of graphitiza-
Electronic properties of graphite: A unified theoretical study
1982年3月15日 · Whereas previous calculations of the electronic band structure of graphite provide explanations either for moderate- to high-energy excitations or for low-energy and Fermi-surface properties, we find excellent agreement between …
Graphene, a one atom thick crystal of carbon arranged in a two-dimensional (2d) honeycomb lattice, posses extraordinary electronic properties. Its charge carriers are quasiparticle whose motion, being governed by the Dirac-Weyl equation, mimics that of quantum relativistic particles (massless Dirac fermions) in (2+1) dimensions[1-6].
First-principles study of the electronic properties of graphite
1991年2月15日 · The electronic properties of hexagonal graphite have been studied in the framework of the density-functional technique, using nonlocal ionic pseudopotentials and a large number of plane waves.
Electronic Band Structure and Optical Properties of Graphite …
The electronic band structure of graphite has been calculated from an ab initio variational approach using a linear-combination of atomic-orbitals (LCAO) basis of Bloch states, including nonspherical terms in the one-electron crystal potential.
Mixing of moiré-surface and bulk states in graphite - Nature
2023年7月19日 · Here we show that electronic states in three-dimensional (3D) crystals such as graphite can be tuned by a superlattice potential occurring at the interface with another crystal—namely,...
