Abstract

SiC@SiO2 nanocables (NCs) were annealed under a nitrogen flow at 1400 °C. Structural and chemical characterization by SEM, HRTEM, EDX, and XRD show that the heat treatment led to the dewetting of SiO2 and the formation of SiC/SiO2 pearl necklace-like nanostructures (NSs). The dewetting mechanism has been attributed mainly to the Rayleigh instability. These NSs could have a wide range of applications in different fields such as nanocomposites, electronics, sensors, drug release, and light emitting diodes.
