Arc discharge is commonly used for the synthesis of carbon nanotubes (CNTs), even though not much is known concerning the process itself and the role of the discharge parameters on the formation of different kinds of nanostructures. We have investiga

Publikováno v: Journal of Non-Crystalline Solids. 356:1948-1950

Si nanocrystals were synthesized and deposited on HOPG substrates. Using micro-Raman spectroscopy, we demonstrate that significant laser heating may be induced on Si nanocrystals, leading to an increase in the local temperature. As a consequence, the
