 | Liu, Feng | Equilibrium shape of two-dimensional islands under stress | We show that the equilibrium shape anisotropy of two-dimensional islands in heteroepitaxial growth depends on island size, a consequence of the presence of strain. Even in homoepitaxy, in which the island shape has conventionally been equated with the ratio of step energies, a substrate surface str... | Two-dimensional islands; Equilibrium shape; Heteroepitaxial growth; Homoepitaxy | 2000-08 |

 | Liu, Feng | Surface stress-induced island shape transition in Si(001) homoepitaxy | A low-energy electron microscopy study of two-dimensional Si(001) island shapes near thermal equilibrium on 10315 mm2 large single-domain terraces reveals a continuous increase of island aspect ratio and a shape transition from elliptical to ‘‘American-football''-like with increasing island size... | Si(001); Homoepitaxy; Island shape transition; Single-domain terraces | 2001-11 |
