Investigation of the Impact of Point Defects in InGaN/GaN Quantum Wells with High Dislocation Densities

In this work, we report on the efficiency of single InGaN/GaN quantum wells (QWs) grown on thin (<1 µm) GaN buffer layers on silicon (111) substrates exhibiting very high threading dislocation (TD) densities. Despite this high defect density, we show that QW emission efficiency significantly incr...
