Liu, Feng | Bending of nanoscale ultrathin substrates by growth of strained thin films and islands | Mechanical bending is ubiquitous in heteroepitaxial growth of thin films where the strained growing film applies effectively an "external" stress to bend the substrate. Conventionally, when the deposited film is much thinner than the substrate, the bending increases linearly with increasing film th... | Nanoscale ultrathin substrates; Strained thin films; Islands; Heteroepitaxial growth; Si substrate; Ge film | 2005-08 |

Liu, Feng | Critical epinucleation on reconstructured surfaces and first-principle calculation of homonucleation on Si(100) | We introduce the concept of ‘‘critical epinucleation'' to distinguish nucleation on surfaces with and without reconstruction. On a reconstructed surface, the critical classical nucleus is stable against dissociation, but may not yet break the underlying surface reconstruction. Consequently, ther... | Critical epinucleation; First-principle calculation; Homonucleation; Si(100); Islands | 2005-09 |
