Abstract
The impurity ground state wave function and energy, as well as electron binding energy are obtained in ZnS/InP/ZnSe core/shell/shell spherical quantum dot using the variational method. Considering the band structure of the system it is assumed that electron is localized in InP shell. Two parametrical potential is chosen as a confinement potential for the shell. It is assumed that the impurity is located in the center of quantum dot core (ZnS).
