Direct synthesis of -SiC and h-BN coated -SiC nanowires
Résumé
-Silicon carbide (-SiC) nanowires (NWs) have been grown by thermal treatment of commercial silicon particles disposed in a graphite crucible under nitrogen atmosphere. By the same way, treatment under argon of a mixture of a boron nitride (BN) based powder and silicon particles led to h-BN coated -SiC nanowires. The structures of both nanoobjects have been investigated by HRTEM, EDX and EELS
