WebOne of the primary goals in nanomaterials science is to be able to design and grow structures with specific sizes, shapes and spatial orientations, since many active device applications that are anticipated for nanomaterials require a significant degree of control... Web3 Dec 1999 · These results are consistent with an anomalous coarsening model for island growth. The formation of self-assembled islands, or quantum dots, during the epitaxial growth of Ge on Si is characterized by several distinct island shapes and an unusual island size distribution.
