STM images of temperature effect.
(a) STM image of 0.039 ML Bi coverage. (b) Annealed STM image of Fig. 4a. (c) Line profile measurements of (a) and (b). (d) dI/dV spectrum of Bi NCs at room temperature. The image size is 20 × 20 nm2 and the image conditions are Vs = 0.74 V, I = 0.15 nA for (a) and Vs = 0.85 V, I = 0.15 nA for (b).
