Preferred Abstract (Original): 
Polarizabilities of shallow donors and accepters in infinite-barrier GaAs/Ga1-xAlxAs quantum wells have been calculated using the Hasse variational method within the effective mass approximation. The effect of spatially dependent screening on polarizabilities is taken into account with an r-dependent dielectric response. The effects of electric and magnetic fields are also presented.
