Broad emission band in GaN epitaxial layers grown on 6H-SiC and sapphire

Mid-band-gap emissions in GaN epilayers grown on 6H-SiC and sapphire are studied by time-resolved spectroscopy (TRS). The yellow luminescence peaking at ca. 2.2 eV at low-temperature shifts to higher energies with increasing temperature. The presence of emission with the same characteristics in samp...
