Ionization-induced annealing of pre-existing defects in silicon carbide

Atomic-Resolution Investigation of Irradiation-Induced Defects in Silicon Carbide

Silicon carbide (SiC) possesses excellent radiation tolerance, thus, SiC and its composites are promising materials for current and future nuclear systems [1]. However, the atomistic processes that underlie the irradiation response are not sufficiently understood, due largely to the limited spatial resolution of conventional analytical tools. Comparing aberration-corrected scanning transmission...

Nonlinear optical imaging of defects in cubic silicon carbide epilayers

Silicon carbide is one of the most promising materials for power electronic devices capable of operating at extreme conditions. The widespread application of silicon carbide power devices is however limited by the presence of structural defects in silicon carbide epilayers. Our experiment demonstrates that optical second harmonic generation imaging represents a viable solution for characterizin...

Probing the Nature of Annealing Silicon Carbide Samples for Solar Cell

SiC powder preparation using Sol-Gel method. The size of nano-particles grows as the temperature exceeds 900° C. Size of probable agglomerations produced, is approximately less than 50nm. The surface is suitable to be used for dye solar cells. SiC emission occurs at wavelength area of 11.3μm or wave number area of 884.95 cm-1. In this paper probing the nature of annealed SiC samples in mixture,...

Rapid thermal annealing and crystallization mechanisms study of silicon nanocrystal in silicon carbide matrix

In this paper, a positive effect of rapid thermal annealing (RTA) technique has been researched and compared with conventional furnace annealing for Si nanocrystalline in silicon carbide (SiC) matrix system. Amorphous Si-rich SiC layer has been deposited by co-sputtering in different Si concentrations (50 to approximately 80 v%). Si nanocrystals (Si-NC) containing different grain sizes have bee...
