Effect of 3C-SiC irradiation with 8 MeV protons
2016
Effects of proton irradiation in n-3C-SiC grown by sublimation on a 4H-SiC substrate have been studied by the Hall effect and photoluminescence methods. It was found that the carrier removal rate (Vd) reaches a value of ∼110 cm −1 . The full compensation of samples with an initial concentration of (1–2) × 10 18 cm −3 was estimated to occur at doses of about 6 × 10 15 cm −2 . Compared with 4H and 6H silicon carbide, no significant increase in the intensity of so-called “defective” photoluminescence was observed in 3C-SiC.
