Abstract	Magnetic field induced binding energy of two donors in a parabolic GaAs/AlGaAs nano dot is reported. The calculations are carried out using variation ansatz within the single band effective mass approximation. The binding energy is estimated for different inter-impurity distances in the presence of magnetic field. The correlation effect of two donors is introduced through the wave function. It is found that inter-impurity distance, correlation of donors and the magnetic field strength make the electron more binding.
