| titleOfInvention | Group III Nitride Semiconductor Light-Emitting Device And Production Method Therefor |
| abstract | The present invention provides a Group III nitride semiconductor light-emitting device exhibiting improved emission performance. A light-emitting layer has a MQW structure in which a plurality of layer units are repeatedly deposited, each layer unit comprising a well layer, a protective layer, and a barrier layer sequentially deposited. The protective layer has a layered structure comprising a second protective layer disposed in contact with and on the well layer, and a first protective layer disposed in contact with and on the second protective layer. The second protective layer is formed of GaN. The first protective layer is formed of AlGaInN. The first protective layer has a bandgap larger than that of the well layer and not larger than that of the barrier layer. Moreover, the first protective layer has an In composition ratio of more than 0% and not more than 4%. |
