Abstract
The microstructure of the Si nanocrystals (Si nc) has been investigated using conventional and high-resolution transmission electron microscopy (HRTEM). For most of the nanocrystals larger than 10 nm, HRTEM observations show that they are formed by the coalescence of smaller ones. Two kinds of coalescence, one being the preferential attachments of small particles to the {111} facets of a seed nanoparticle, and the other being an ordered combination of two or more small nanocrystals with appropriate orientations, have been observed.
