But as the well width increase, level filling is the main reason for the red-shift of spectrum, Augerrecombination and carrier delocalization are the main reason for lower efficiency.
当阱宽较大时,能级填充是导致光谱红移的主要原因,俄歇复合与载流子离域是导致效率下降的主要原因。

They have many interesting physical properties, such as symmetric band structure, strong temperature dependences of energy gaps, absence of a heavy hole band, and low Augerrecombination rates, etc.
