The Piecewise Diffusion of the Silicon Dimer (1843 words) |
 | However, the distribution of dimers occupying the two types of sites upon formation is kinetically determined: one third form on rows and two thirds form in troughs [6]. |
| Because of the strong anisotropy of the Si(001) reconstructed surface, diffusion is strongly one dimensional. |
| The dimer dissociates as one atom moves ahead, and the two atoms move up and down the trough independently until they meet again and reform the dimer in a new location. |
| IFS Attractors: dimers (2D) (2115 words) |
| Of all rep-tiles the dimers are the easiest to enumerate, as there are just 4 independent parameters, the angles by which each element is rotated with respect to the whole figure, and whether each element is directly or inversely similar to the whole figure. |
| Even with the restricted phase space of the set of dimers an exhaustive search would be time consuming, so investigation of the set of dimers has to be based on theoretical and heuristic grounds. |
| Of the 12 distinct figures, 8 are amongst the 10 figures identified as dimers. |
