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 Auger recombination rates, etc.

它们具有很多独特的物理性质：对称的能带结构、强烈依赖于温度的带隙、一个重空穴带的缺失、低的俄歇复合率等。

But as the well width increase, level filling is the main reason for the red-shift of spectrum, Auger recombination 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。
