Keywords: quantum dot, exciton complex, binding energy

Binding energies for an exciton (X) trapped in the two-dimensional quantum dot by a charge impurity located on the z axis at a distance from the dot plane are calculated by using the method of few-body physics. This configuration is called a varrier (D+,X) center or a barrier (A-,X) center. The dependences of the binding energy of the ground stat of the barrier (D+,X) and (A-,X) centers on the electron-to-hole mass ratio s and the dot radius R for a few values of the distance d between the fixed positive ion on the z axis and the dot plane are obtained.
