WebJan 1, 2011 · The ABC-stacked graphite owns linear and parabolic energy bands with strong anisotropy. Energy bands may be non-degenerate as well as double, triple, and six-fold. Each band has many band-edge states contributing to the high density of states. Such states are located near or at the high symmetry points. WebMar 5, 2024 · A material’s ability to conduct electricity is normally represented in terms of energy bands. A single band represents a range of energies that a material’s electrons can have. There is an energy gap between bands, and when one band is filled, an electron must embody extra energy to overcome this gap, in order to occupy the next empty band.
