STM empty-state images of hut nuclei on Ge WL formed at different temperatures: a pyramid (1) and wedge (2) nuclei on the adjacent M × N patches of WL; Tgr = 360°C, hGe = 6 Å; the structural models [20,32] are superimposed on the corresponding images in a; b, c pyramid nuclei on WL formed at low temperature (Tgr = 360°C): b hGe = 5.4 Å; c hGe = 6 Å; d, e a pyramid nucleus on WL formed at high temperature, hGe = 5 Å: d Tgr = 600°C, 43 × 37 nm; e Tgr = 650°C, 7.8 × 6 nm.
