Donor-Acceptor Pair Luminescence of Phosphorus-Aluminum and Nitrogen-Aluminum Pairs in 4H SiC
The procedure of fitting the spectra associated with donor-acceptor pair luminescence arising from nitrogen-aluminum and phosphorus-aluminum pairs in 4H SiC is described in detail. We show that the fitting can be used not only for accurate evaluation of the ionization energies of the different donors and acceptors involved, but also for unambiguous determination of their lattice sites.
