Carrier statistics of highly doped armchair graphene nanoribbons with edge disorder

A first-principles study of bilayered black phosphorene as a potential anode material for sodium-ion batteries

“…The DOS suggests that Na adsorption makes all BBPs originally being semiconductors to exhibit metallic features, which provides a good electrical conductivity required for an ideal anode. According to the DOS, the carrier concentrations can be estimated by the following equations: 77–82 n ( E ) = DOS( E ) f E f ( E ), p ( E ) = DOS( E )[1 − f E f ( E )].where n ( E ) and p ( E ) denote the electron concentration and the hole concentration, respectively. is the Fermi function which gives the probability of finding an electron in energy E .…”
