摘要:

利用多带Luttinger模型的球近似方法计算了量子点中含有受主杂质离子的空穴能谱。研究了量子点中空穴能级与杂质位置的关系。分析了杂质位置对偶极动量和振子强度的影响。计算了空穴的层间吸收系数。

英文摘要:

The hole energy spectrum with the ion of an acceptor impurity in the quantum dot has been calculated using the spherical approximation of the multiband Luttinger model. The dependence of the hole energy levels on the impurity location in the quantum dot has been studied. The effect of the impurity location on the dipole momentum and the oscillator strength has been analyzed. The hole interlevel absorption coefficient has been calculated.
