Could you please clarify your question? what kind of materials and what kind of synthetic procedure are you interested in? try to be more specific
Dear F. Caballero-Briones
Thanks for your efforts.
The material is boron nitride and the synthetic procedure is CVD or related chemical procedure.
Dear Pervaiz
In CVD there are important parameters to prepare nanostructures o nanostructured materials. One of these is the substrate, either you use a crystalline substrate or an amorphous one it would affect the growth habit, the stress and so on. Another parameter if you want to prepare nanostructures is the use of seeds. Ofter nickel, platinum or another inert metal nanoparticles deposited onto the substrate are used as seeds, so particle sizes, shapes and distribution onto the substrate have to be accounted. The precursor are another parameter: I am not familiar on boron nitride but I assume that different precursor can be used, then its chemical identity (related with the decomposition point, decomposition kinetics and reaction mechanis) as well as the relative fluxes, pressures would influence the deposition. In CVD the temperature is crucial: if your reactor has zones you can vary ramps, thermal gradients and so on.
I hope it is useful for you. Regards.
Type of precursors, temperature and optimization of surfactants would surely results in different kind of nanostructures.
