| 中文摘要 | Using first-principles total-energy calculations, we have systematically investigated the adsorption and diffusion of Ga dimers on Si(001) to form dimer linear chains (DLC) perpendicular to the surface dimer rows. We find that Ga dimers prefer forming DLC on Si(001) both energetically and kinetically with an anisotropy diffusing pathway, and the energy barriers for Ga dimers diffusing across or along the surface dimer rows along certain paths can be significantly reduced by the interaction of Ga dimers. As a result, Ga dimers can easily diffuse into the most stable sites to form one-dimensional DLC. These results reveal a natural explanation for the relevant experimental observation. |
