 | Liu, Feng | Unique dynamic appearance of a Ge-Si Ad-dimer on Si(001) | We carry out a comparative study of the energetics and dynamics of Si-Si, Ge-Ge, and Ge-Si ad-dimers on top of a dimer row in the Si(001) surface, using first-principles calculations. The dynamic appearance of a Ge-Si dimer is distinctively different from that of a Si-Si or Ge-Ge dimer, providing a ... | Ge-Si Ad-dimer; Si(001); First-principles calculations; Energetics | 2000-12 |
