Left panel: The parameter as function of The curves are plotted using Eq. (22) and assuming a = 10 (dashed line), a = 1 (solid line) and a = 0.1 (dashed-dotted line). For weak electrostatic interactions on the left interface takes on values much greater then 1 being proportional to When these interactions are strong asymptotically approaches zero and could be approximated by Right panel: The ratio versus the ratio of areal charge carriers densities on the substrates. The values taken by vary over a broad range indicating that strong electrostatic interactions between the MLG and the substrate at one interface may coexist with weak interactions at another interface. When regardless of the interaction strength.
Location of the electroneutrality level in a twisted MLG film placed in between two charged substrates with the areal charge densities and at the interfaces z = – D/2 and z = D/2, respectively. Thepresented surfaces are built assuming (top panel); (lower panel).
Spatial profiles of the scaled electrostatic potential inside the MLG film as functions of the normalized distance into the film plotted using Eq. (32) . Left panel: a = 1 and (dashed-dotted line), (dashed line) and (solid line). Right panel: and a = 1 (dashed-dotted line), a = 0.25 (dashed line) and a = 0.1 (solid line).
