Terahertz study of ultrafast carrier dynamics in InGaN/GaN multiple quantum wells
Ultrafast carrier dynamics in InGaN/GaN multiple quantum wells is measured by time-resolved terahertz spectroscopy. The built-in piezoelectric field is initially screened by photoexcited, polarized carriers, and is gradullay restored as the carriers recombine. We observe a nonexponential decay of the carrier density. Time-integrated photoluminescence spectra have shown a complete screening of t...
متن کاملStructural and optical emission characteristics of InGaN thin layers and the implications for growing high-quality quantum wells by MOCVD
Defect formation and In segregation in InGaN/GaN quantum wells grown at various temperatures and with various well thicknesses were studied using cathodoluminescence, transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HR-TEM). In 0.16 Ga 0.84 N quantum wells with In compositional nonuniformity and a small number of structural defects originating at the ...
متن کاملEmission dynamics of red emitting InGaN/GaN single quantum wells
Emission dynamics of two InGaN/GaN single quantum well red emitters were investigated through timeresolved photoluminescence (PL) spectroscopy. A clear phase separation, where a higher energy (blue) emission and a lower energy (red) emission appear simultaneously, was observed. The maximum position of blue emission is consistent with the bandgap value of the InGaN quantum well. As the time afte...
متن کاملEffects of reduced exciton diffusion in InGaN/GaN multiple quantum well nanorods.
We investigate the effects of reduced exciton diffusion on the emission properties in InGaN/GaN multiple-quantum-well nanorods. Time-resolved photoluminescence spectra are recorded and compared in dry-etched InGaN/GaN nanorods and parent multiple quantum wells at various temperatures with carrier density in different regimes. Faster carrier recombination and absence of delayed rise in the emiss...
متن کاملInGaN/GaN multiple quantum wells grown on nonpolar facets of vertical GaN nanorod arrays.
Uniform GaN nanorod arrays are grown vertically by selective area growth on (left angle bracket 0001 right angle bracket) substrates. The GaN nanorods present six nonpolar {1⁻100} facets, which serve as growth surfaces for InGaN-based light-emitting diode quantum well active regions. Compared to growth on the polar {0001} plane, the piezoelectric fields in the multiple quantum wells (MQWs) can ...
