Abstract
We have performed electrical and optical measurements to characterize the processes of radiative recombination of carriers for 4H-SiC p-n(+) junctions. We have detected three levels in the band gap, using capac itance and current deep-level transient spectroscopy, which are respon sible for the bands observed in the electroluminescence spectra. We as sume that the HK1 center with an activation energy of E(V) + 0.229 eV and a hole capture cross-section of 8 x 10(-13) (300/T)(3) is related to the Al acceptor level.
