ScholarBank@NUS Repository. https://doi.org/10.1088/0957-4484/13/6/303 | Abstract: | The nucleation and growth of Si and Ge clusters/crystallites on SiNx films, which act as relative inert substrates, proceed in a quite complicated manner compared with conventional epitaxial processes. We examine the size dependence of the shape, surface structures and orientation of nano-scale clusters/crystallites. Facets are not observed until the crystallite diameter reaches ∼40 nm. Due to the isotropic surface energy and a weak interaction with the substrate, the orientation of the clusters/crystallites is random initially. A preferred orientation, however, emerges on crystalline SiNx films as the crystallite size increases. The growth nature of nano-particles, their interactions with the substrates and among themselves determine the overlayer texture as the amount of material deposition increases. | Source Title: | Nanotechnology | URI: | http://scholarbank.nus.edu.sg/handle/10635/98873 | ISSN: | 09574484 | DOI: | 10.1088/0957-4484/13/6/303 |
