Analysis of the effect of polarization traps and shallow impurities on the interlevel light absorption of quantum dots
A spherical quantum dot (QD) heterosystem CdS/SiO2 has been studied. Each QD has a hydrogen-like impurity in its center. Besides that, it has been accounted that a polarization trap for electron exists at the interfaces due to the difference between the QD and matrix dielectric permittivity. It has...
