STM images of Ge WL on Si(001): T_{gr }= 360°C, the ordinary c(4 × 2) (c) and p(2 × 2) (p) reconstructions within the M × N patches are often observed simultaneously, a h_{Ge }= 4.4 Å, U_{s }= -1.86 V, I= 100 pA, only the _{t }c(4 × 2) structure is resolved; b h_{Ge }= 5.1 Å, U_{s }= -3.78 V, I= 100 pA, both _{t }c(4 × 2) and p(2 × 2) structures are revealed as well as nuclei of a pyramid (1) and a wedge (2);
c, d h_{Ge }= 6.0 Å, U_{s }= +1.80 V, I= 80 pA, both _{t }c(4 × 2) and p(2 × 2) reconstructions are well resolved; e h_{Ge }= 5.1 Å, U_{s }= -3.78 V, I= 100 pA, a pyramid nucleus on the _{t }c(4 × 2) reconstructed patch with the adjacent p(2 × 2) reconstructed patch.
