Extended Data Fig. 1: Calculated band structure of MATNG in the presence of electric displacement field \(\frac{D}{{\varepsilon }_{0}}=0.5\) V/nm.
From: Robust superconductivity in magic-angle multilayer graphene family

The calculation uses the screened electrostatic potential calculated as illustrated in Extended Data Fig. 6c. For all N>2 MATNG structures, the electric displacement field hybridizes the flat bands with other dispersive bands.
