WebQuestion: 2. Graphene is a one atomic layer thickness (2 dimensional) carbon structure with zero band gap at charge neutrality point (also called Dirac point) and the effective band gap is proportional to the applied gate voltage (band diagram is shown below) and the Fermi level goes up or down depending on the gate voltage polarity. 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 … WebAug 9, 2011 · Graphene Conductivity near the Charge Neutral Point.
