Ks. Kim et al., GROWTH MODE OF AU LAYER ON SI(001), Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 117(3), 1996, pp. 289-294
We investigated the annealing effect on the behavior of Au atoms on th
e Si(001) surface using coaxial impact collision ion scattering spectr
oscopy. We found that the growth mode of Au atoms on Si(001) at room t
emperature is layer by layer growth, whereas Au atoms on Si(001) are t
ransformed into three dimensional islands above 400 degrees C. We foun
d that the structure of the Au islands is a crystalline {001} orientat
ion with the [110] direction aligned with a [100] direction in the sub
strate. The crystalline portion of the islands is about 42% of the top
two atomic layers.
