Figure 3: Temperature-dependent charge ordering.

(a–c) STM topographic showing the very same location of the sample surface at T=33, 49 and 67 K. Scale bars, 20 nm. One island is marked by white arrows. (d) Rendered perspective images as seen along the viewing direction marked by a black arrow in a. Although the stripes are clearly visible at low and high temperatures (see, for example, the area in front of the island marked by a white arrow), the intensity is strongly reduced at the intermediate temperature. (e) Plot of the temperature-dependent normalized intensity of the spots indicative for the stripe pattern (see arrow). A dip starting at around T=70 K can be recognized. An example of a Fourier-transformed STM image taken at T=85 K is shown in the inset. Error bars represent the spot’s full width at half maximum after subtraction of the background intensity. Scale bar, 1 nm−1.
