The ground state energy of exciton bound by distant ionized donor impurity in two-dimensional semiconductor quantum well (QW) is studied theoretically within the Hartree approach in the effective mass approximation. The influence of the distance between QW plane and ionized donor, as well as of the electron-hole mass ratio, the magnetic field aligned across the QW plane and dielectric constant of the barrier material on the stability of exciton bound by ionized donor impurity is analyzed and discussed.
