Using a novel variational wave function for the ground state of the shallow donor in a narrow GaAs/Ga1-xAlxAs quantum-well, we have calculated the wave function and the binding energy for impurity ground state. The numerical results shown that it is important to describe the coupling between the narrow quantum-well and the impurity potential correctly.
