Fig. 74: 00L scans, between 2 Bragg peaks, at a few annealing temperatures. The number of monolayers (ML) is deduced from the Kiessig fringes frequency. The 3 regions correspond to that of the "kscan" map (Fig. 73b): in region 1 the thickness keeps 9 ML, then it increases to 15 ML in region 2 and it switches to 23 ML after the transition (around 400 °C) in region 3.
