Fig. 2: STM images of the MnBi2Te4 surface.
From: Native point defects and their implications for the Dirac point gap at MnBi2Te4(0001)
Large scale STM topographic images of the MnBi2Te4 Te-terminated (0001) surface after in situ cleavage showing a flat terraces separated by an SL thick step (2 V and 0.5 nA, scale bar 25 nm) and b its corresponding line profile. c STM image of a representative area far from the step where the characteristic density of surface defects can be observed (1 V and 0.1 nA, scale bar 25 nm). Inset: Zoom of 2.5 nm2 of one of the triangular-shaped defects taken at 1 V and 0.1 nA.
