WebThe figure has been generated by adding the electron sheet density -n and the hole sheet density p (taking into account that the electron density is negative) for each voltage point. Multiplied by the electron charge e , this gives the electron density in units of [As/cm 2 ]: Q = -n + p Then plot Q vs. V. WebWe calculated the integrated local density of states profile ρ ( z) of single-layer graphene in the energy range E ∈ [−3, 3] eV from the charge neutrality point at Ec = 0 eV. In this energy range, the bands are of pure p z orbital character without contributions from the s-, p x - and p y -like orbitals).
