(a) Model of a H-Si(100) surface with silicon atoms in yellow and hydrogen
atoms in white. (b) Constant-current STM image of a H-Si(100) surface. Dimer rows
are visible in the vertical direction and the atom separation along and across dimer
rows are marked. Some dimer bonds are also marked by an overlaid grid of black bars
(Color figure online).
