SiO₂ layer prevents direct contact between Si particles, inhibiting long-distance electron migration and reducing dielectric loss
SiO₂ introduces traps to immobilize charge carriers, elevating breakdown strength
Crystalline SiO₂ shell accelerates phonon transport, leading to enhanced thermal conductivity
Dielectric parameters and thermal conductivity can be synergistically tuned by adjusting SiO₂ morphology and thickness
