On these Ga-doped samples, all experimental spectra collected at 5K were found dominated by strong N-Ga donor-acceptor pair (DAP) transitions and phonon replicas. As expected, the N-Ga DAP zero-phonon line (ZPL) was located at lower energy (similar to 86 meV) below the N-Al one. Fitting the transition energies for the N-Al close DAP lines gave 251 meV for the Al acceptor binding energy in 3C-SiC and, by comparison, 337 meV for the Ga acceptor one. %G English %L hal-00543685 %U https://hal.science/hal-00543685 %~ CEA %~ CNRS %~ UNIV-LYON1 %~ UNIV-MONTP2 %~ GES %~ LMI %~ DRT %~ UNIV-MONTPELLIER %~ LETI %~ CEA-GRE %~ UDL %~ UNIV-LYON %~ UM1-UM2 %~ TEST2-HALCNRS
