Effects of Neutron Flux on the Temperature Dependency of Permittivity of 3C-SiC Nanoparticles

In the present work, the real and imaginary parts of permittivity of cubic modification silicon carbide (3C-SiC) nanoparticles are investigated before and after neutron irradiation. The real and imaginary parts of permittivity for the samples were studied in 0.1 Hz-2.5 MHz frequency and 100 K-400 K temperature ranges. The samples were continuously irradiated by neutron flux (2x10(13) n.cm(-2) s(-1)) up to 20 hours. The real and imaginary parts of permittivity were comparatively studied before and after irradiation. Neutron irradiation effects were studied with comparative analysis of non-irradiated samples. The increase in polarization was observed as a result of the increase in the impact period of neutron flux. All the mechanisms of the observed effects are given in the work.
