Abstract
Binding energy of neutral (D(0)) and negatively charged (D(-)) hydrogenic impurity located at the center of the CdTe/ZnTe spherical quantum dot has been investigated. Calculations are performed under the effective mass approximation on the basis of exact solution of the Schrödinger and Poisson equations. Eigenfunctions are expressed in terms of the Whittaker and Coulomb wave functions. Calculated results show that D(0) and D(-) impurity binding energies of ground 1s, 1S(1s2) and 2p, 3P(1s2p) excited states strongly depend on CdTe/ZnTe QD size if QD radius is less than one effective Bohr radius.
