Abstract

En 中文

• Gamma radiation significantly increases conductivity in CVD-SiC. • Radiation-induced conductivity shows linear dependence on dose rate. • Baseline conductivity increases rapidly below 10 kGy cumulative dose. • Gamma irradiation causes surface melting and carbon phase formation. • Electrical degradation linked to SiOxC3−x surface structural changes.
