From: CMOS-compatible dense arrays of Ge quantum dots on the Si(001) surface: hut cluster nucleation, atomic structure and array life cycle during UHV MBE growth

Figure 8

STM 2D and 3D images of the same area on a Ge hut cluster facet: (a) 2D micrograph and (b) 3D topograph; h Ge = 10Å, T gr = 360°C, U s = +2.1 V, I t = 80 pA. The sides of the cluster base lie along the [100] direction; structural units revealed on the free surfaces of the (001) terraces and interpreted as PD are marked out.
