From Figures 3b and 4b, we can see that the enhancement of the electric field and accumulation of opposite charge transfer from the edges and corners of CW towards the splits Subsequent, the individually tunable properties from the device are analyzed.

Prior research have shown that the graphene Fermi level may be modulated to be 1.two eV [34]. When the Ferm level increases to 1.two eV, peak I disappears totally, which causes an off state. In an effort to quantitatively describe the modulation depth of the PIT transparent windows, we in-Nanomaterials 2021, 11,5 offunction at two PIT windows might be realized by tuning the graphene Fermi level.
