| The high resolution STM image and structural model of clean Si(3 × 3)/Ag(4 × 4)- α phase. (a) A typical STM image (14 nm×11 nm in size). In the upper-right part of the image there is a small area consisting of a metastable- β phase. The white rhombus and the red rhombus mark the α -4 × 4 and β -4 × 4 unit cells, respectively. (b) Structural model of α -4 × 4. Each unit cell consists of 6 upper-buckled Si atoms and the two HUCs are mirror-symmetric (adapted from Ref. [ 15 ]). |
