Twist Gating of a Graphene Nanoribbon
Abstract Employing first‐principles calculations and the non‐equilibrium Green's function method, a hexa‐peri‐hexabenzocoronene nanoflake is investigated on an armchair graphene nanoribbon. It turns out that a current modulation of up to 25% can be achieved by twisting of the nanoflake due to m...

| description | Abstract Employing first‐principles calculations and the non‐equilibrium Green's function method, a hexa‐peri‐hexabenzocoronene nanoflake is investigated on an armchair graphene nanoribbon. It turns out that a current modulation of up to 25% can be achieved by twisting of the nanoflake due to modulated scattering as a consequence of changes in the orbital overlap. The effect of twist gating is reminiscent of current control by electrostatic gating with a large variety of potential applications. |
