TL;DR: In this article, the effect of polarization field on the efficiency droop in InGaN/GaN multiple quantum wells (MQWs) was investigated and solutions to prevent or reduce the efficiency drop in GaN-based LEDs as well.

TL;DR: In this paper, the 17O NMR measurements were conducted on electrolyte solutions consisting of Li[CF3SO2NSO2CF3] (LiTFSI) dissolved in the solvents of ethylene carbonate (EC), PC, EMC and their mixtures at various concentrations.

TL;DR: In this paper, the authors present a testing scheme using controlled buckling experiment to determine the fracture toughness of brittle thin films prepared on compliant substrates, where critical fracture strain can be calculated by measuring the displacement of the buckled plate.

TL;DR: Results indicate that the SEED can provide better spatial resolution compared to state-of-the-art SR reconstruction algorithms in SPEN MRI and theoretical analysis and experimental results show that the SR images reconstructed by SEED have better spatialresolution than the images obtained with conventional k-space encoding methods under similar experimental condition.

TL;DR: In this paper, an approach by adjusting electrical currents of three-primary light-emitting diodes (RGB-LEDs) to tune the CAF and color coordinates to be close to those of the standard light with various correlated color temperature (CCT) (2700 K-6500 K) has been reported.
