Liu, Feng | Seeing the atomic orbital: first-principles study of the effect of tip termination on atomic force microscopy | We perform extensive first-principles calculations to simulate the topographical atomic-force-microscope image of an adatom on the Si(111)-(7 X 7) surface, demonstrating the feasibility of imaging not only the atoms but also the atomic orbitals. Our comparative study of tip terminations shows that ... | First-principles; Tip termination; Adatoms | 2003-06 |

Smith, Grant D.; Bedrov, Dmitro; Borodin, Oleg | Structural relaxation and dynamic hetrogeneity in a polymer melt at attractive surfaces | Molecular dynamics simulations of polymer melts at flat and structured surfaces reveal that, for the former, slow dynamics and increased dynamic heterogeneity for an adsorbed polymer is due to densification of the polymer in a surface layer, while, for the latter, the energy topography of the sur... | Polymer melts; Structural relaxation; Dynamic heterogeneity; Attractive surfaces; Surface energy topography; Polymer densification | 2003-06 |
