Extended Data Fig. 4: Chern insulator signal dependence on the displacement field.
From: Direct magnetic imaging of fractional Chern insulators in twisted MoTe2
(a) Signal δBn as a function of charge carrier density and electric displacement field; (b) Minimum value of δBn in a window around ν = − 1 gap along displacement field axis. The positions of the values are shown on a. The signal from the gap decays slightly as a function of displacement field, remaining finite up to the first order phase transition induced by layer polarization.
