Webb1 aug. 2000 · The thermovoltage in Fig. 6(b) clearly shows variations on the atomic scale but it does not simply correspond to the topography. As expected the adatoms of the 7×7 reconstruction appear in the thermovoltage since the corresponding surface state is located around E F; hence, it contributes most to the tunneling at zero bias voltage. Webb28 mars 2024 · The thermovoltage of each sample was measured twice by varying the thermal gradient in two different ranges. The ten small panels in Figure 7 a show, for all the samples, the thermovoltage plotted against the applied thermal gradients in the range 15–70 °C (top graph) and in the range 30–60 °C (bottom graph).
