Description

We present the results of DLTS investigation of as-grown and radiation-induced defects in n-type 4H-SiC Schottky diodes irradiated with different fluences of 6 MeV electrons. The only variable between the samples has been the irradiation fluence, varying from unirradiated state up to fluences as high as 6E14 e/cm2. The DLTS spectra were analyzed and simulated to extract the defect parameters. The study also examined the annealing behavior of defects up to 750 K (~477°C).

The results are correlated with current literature and discussed in terms of defect evolution, thermal stability and possible chemical identification.
