Phosphorus-related luminescence in SiC
2006 (English)In: Physica Scripta, Vol. T126, 2006, Vol. T126, 45-49 p.Conference paper (Refereed)
We report a photoluminescence (PL) study from n-type phosphorus-doped SiC epilayers, which reveals a PL spectrum constituted by a set of sharp lines and interpreted as excitons bound to the P donor. Depending on the polytype, the PL spectrum consists of one or several zero-phonon lines, which have photon energies very close to the nitrogen-bound excitons and they are followed by their phonon assisted replicas. The intensity of the PL spectrum depends on the P concentration introduced during the growth of the epilayers but can be reduced by the presence of the nitrogen donor.
