Raman spectra showing doublets with two peaks at 1586 and at .
Area of about of the -graphite intercalate. The topography is shown on the left side [see (a)], the thermovoltage [see (b)] on the right side. A strong contrast between different areas is found for the thermovoltage. The cross-section 1 and cross-section 2 (see Fig. 3) reveal different correlations between the more HOPG-like and the SeCl4-GIC layers.
(a) represents cross-section 1 taken in Fig. 2. It shows a cut across the three areas B, C, and D in the topography (solid) and thermovoltage (dashed). Subfigure (b) shows cross-section 2 across a rather smooth transition from area A to B in topography (solid) and thermovoltage (dashed).
Model to explain different features in the thermovoltage and the topography. The areas marked with A, B, C, and D correspond to the steps with the same labels in Fig. 2. The model shows a third stage graphite intercalation compound as suggested by Raman spectroscopy.
