Analysis of the effect of polarization traps and shallow impurities on the interlevel light absorption of quantum dots

V. I. Boichuk, R. Ya. Leshko, D. S. Karpyn

A spherical quantum dot (QD) heterosystem CdS/SiO${}_2$ has been studied. Each QD has a hydrogen-like impurity in its center. Besides that, it has been accounted that a polarization…
