ABSTRACTTwo-dimensional arrays of silver nanocylinders fabricated by electron-beam lithography are used to demonstrate plasmon-enhanced near-green light emission from nitride semiconductor quantum wells. Large enhancements in peak photoluminescence intensity (up to a factor of over 3) are obtained, accompanied by a substantial reduction in recombination lifetime indicative of increased internal quantum efficiency. The measured enhancement factors exhibit a strong dependence on the nanoparticle dimensions, underscoring the importance of geometrical tuning for this application.

Nanoscopic optical characterization using scanning near-field optical microscopy was performed on both InxGa1-xN/GaN single quantum wells (SQWs) grown on polar (0001) orientation and a semipolar (1122) microfacet SQW fabricated by a re-growth technique. The photoluminescence intensity of a conventional (0001) SQW emitting in the blue was completely independent of the threading dislocations (TDs) due to the small diffusion length less than 100 nm. In contrast, the photoluminescence intensity was well correlated with the TDs in the sample emitting in the green due to the association of In-rich clusters with dislocations, and the effect was enhanced by the larger diffusion length contribution from the longer radiative recombination lifetime. It was found that in a (1122) SQW, the suppression of the piezoelectric field leads to orders-of-magnitude faster radiative lifetime and consequently, a shorter diffusion length. In addition, the highest internal quantum efficiency was approximately 50% at 520 nm, which is about 50 nm longer than in (0001) QWs, suggesting that (1122) QWs are suitable for green emitters.

ABSTRACTInGaN/GaN multiple quantum wells (MQWs) with [0001], <11.2>, and <11.0> orientations have been fabricated by means of the re-growth technique on patterned GaN templates with striped geometry, normal planes of which are (0001) and {11.0}, on sapphire (0001) substrates. It was found that photoluminescence intensity of the {11.2} QW is the strongest among the three QWs, and its internal quantum efficiency was estimated to be as large as about 40% at room temperature. The radiative recombination lifetime of the {11.2} QW was about 0.39 ns at 14 K, which was 3.8 times shorter than that of conventional c-oriented QWs emitting at a similar wavelength. These findings are well explained by the high internal quantum efficiency in the {11.2} QW owing to the suppression of piezoelectric fields.
