Fig. 4

a, b Typical CO modulations in the Fe3Ge and Ge2 layers of sample #2. c, d Disrupted CO distributions in the same regions of (a, b). CO modulation disappears in the areas enclosed by the orange dashed curves. e, f Corresponding topographic images of (c, d). g Typical topographic image of the Fe3Ge layer in sample #1, exhibiting strong phase separation. h–j Lattice line profiles taken along cuts 1–3. The height difference of the two phases, Δh, is marked out. Measurement conditions: (a–d) Vb = 0.3 V, It = 300 pA, ΔV = 30 mV; (e, f) Vb = 0.3 V, It = 300 pA; (g) Vb = 50 mV, It = 20 pA.
