微分增益系数随薄层载流子密度的增加而降低。
The differential gain coefficient decreases with increased sheet carrier density.
在任何载流子密度条件下,辐射强度与准费米能级差的关系保持不变。
At all carrier densities, the relation between emission intensity and difference of the quasi Fermi energies is maintained.
进一步分析认为,这是因为条宽变窄导致器件阈值电流密度、阈值载流子密度变大造成的。
Further analysis shows that it is caused by the enhancement of the threshold current density and threshold carrier density in terms of optical-gain spe.
