Key Points

The study aims to understand how the interaction of vacancies and silicon-carbon creates defects in β-SiC under irradiation.
Utilized first-principles methods to analyze electron-structure-dynamics coupling.
Examined the role of vacancy-silicon-carbon synergy in defect formation and behavior.
Focused on the effects of irradiation on β-SiC.
Defect accumulation leads to significant swelling and amorphization of β-SiC.
The synergistic interaction enhances the degradation process compared to single vacancies.
Irradiation significantly impacts the structure and dynamics of electron states.

Implication

This first-principles study reveals electron-structure-dynamics interactions in β-SiC, highlighting defect behaviors under irradiation.
