Graphene charge neutrality point
WebOct 6, 2011 · When the charge density n c was tuned near the neutrality point in each gated region, R increased because of the low density of conduction carriers. When two gates were present, this resulted in two intersecting lines of relatively high resistance, and a maximum resistance R max at their intersection, the global charge neutrality point … WebFeb 14, 2024 · We also show the potential single-particle electronic transitions occurring within or to the vacancy. The graphene reservoir is separated by a distance d i n t e r from the dot-containing “active” layer. The position of the vacancy energy levels ε i are determined with respect to the graphene charge neutrality point (μ = E F, set as the ...
