- W2034365029 abstract "ABSTRACT Motivated by the potential advantages that device-quality zinc blende nitrides would offer over their wurtzite coun- terparts for optoelectronic applications, the optical properties of state-of-the-art cubic GaN grown by molecular beam epitaxy on GaAs(OO1) are investigated in detail. In view of the high densities of structural defects being caused bythe large lattice mismatch to the substrate, special attention is paid to the influence of nonradiative recombinationprocesses on the room temperature band-edge luminescence. A detailed analysis of the temperature and excitationdensity dependence of the band-edge recombination allows to determine transition and activation energies. In con- junction with model calculations, the internal quantum efficiency and the (non)radiative lifetimes are estimated. Thedecay times as well as the observed phenomenon of defect saturation are verified by time-resolved photoluminescence studies. Upon pulsed optical pumping, optical gain exceeding 100 cm1 at an excitation energy density of 2OiJcm2is obtained at room temperature.Keywords: GaN, Zincblende Structure, MBE Growth, Band Gap, Photoluminescence, Gain" @default.
