摘要
This paper presents the characterization of the electrically active defects created by epithermal and fast neutrons in epitaxial n-type 4H-SiC material using Laplace Deep Level Transient Spectroscopy (Laplace DLTS). While the deep level related to the carbon vacancy has been observed in as-grown material, we observed that epithermal and fast neutron irradiation introduces additional simple defect complexes, with energy levels at E-c - 0.40 eV and E-c - 0.70 eV.
