Spatially resolved STS across the grain boundary. (Set point: V bias = −0.5 V, I set = 0.5 nA) The upper and lower parts are the R(37/61) and R(19/31) regions, respectively. The spectra show the energy shift of the peaks when the measurement point approaches the boundary. The inset displays the STS line profile. The aqua dashed line labels the boundary of contaminations and the white dashed line labels the Fermi level. The diamonds, squares, and circles represent the three peaks. We observe that the diamonds belonging to the R(19/31) region are shifted from −1.46 V (blue) to −1.28 V (green), and the squares are shifted from −0.78 V move to −0.62 V. For the circles, they shift from −0.29 to −0.22 V, but vanish very near the boundary (deep green curve). In the R(37/61) region, the diamonds are shifted from −1.49 V (red) to −1.34 V (black), and squares from −0.78 to −0.64 V. The circles shift from −0.29 to −0.22 V and also vanish near the boundary (black curve)
