摘要
We benchmarked growth, microstructure and photo luminescence (PL) of (11 (2) over bar2) InGaN quantum wells (QWs) against (0001) and (11 (2) over bar0). In incorporation, growth rate and the critical thickness of (11 (2) over bar2) QWs are slightly lower than (0001) QWs, while the In incorporation on (11 (2) over bar0) is reduced by a factor of three. A small step-bunching causes slight fluctuations of the emission wavelength. Transmission electron microscopy as well as atom probe tomography (APT) found very flat interfaces with little In segregation even for 20% In content. APT frequency distribution analysis revealed some deviation from a random InGaN alloy, but not as severe as for (11 (2) over bar0). The slight deviation of (11 (2) over bar2) QWs from an ideal random alloy did not broaden the 300 K PL, the line widths were similar for (11 (2) over bar2) and (0001) while (11 (2) over bar0) QWs were broader. Despite the high structural quality and narrow PL, the integrated PL signal at 300 K was about 4 x lower on (11 (2) over bar2) and more than 10 x lower on (11 (2) over bar0).
