The Study on the Droop Effect in the InGaN/AlGaInN MQWs With Lattice-Matched AlGaN/InGaN Superlattices Barrier by Highly Excited Photoluminescence Measurement
Publié 2018-01-01Accéder au texte intégralWe have fabricated the InGaN/AlGaInN multiple quantum wells with lattice-matched AlGaN/InGaN superlattices barriers (SL-MQWs). The lattice-matched superlattices promote the formation of the high-quality MQWs and eliminate the large polarization electric field. Highly excited ph...
