Fig. 5: Edge states of bilayer InSe with 7.34° twisting angle.
From: Real-space observation of a time-reversal invariant topological state in twisted bilayer InSe
a–c dI/dV maps of bilayer InSe with 7.34° twisting angle (the dashed lines represent the 2 L step). The scanning bias from up to down is −2.3 V, −2.0 V and −1.8 V with tunneling current 70 pA. d dI/dV curves taken at the Position A and Position B marked in a (the represented curves have been vertically shifted for clarity). e Peaks fitting of corresponding dI/dV curve on Position A in d. f Calculated density of states (DOS) of bulk and edge states of bilayer InSe with 7.34° twisting angle.
