BINDING　ENERGY　OF　THE　SHALLOW　DONOR　IN　（CdTe）_m／（ZnTe）_n　STRAINED　DOUBLE　QUANTUM　WELL

In this paper the binding energy of the shallow.donor in CdTe/ZnTe strained double quantum well was calculated.The effect of the finite well potential and strain,resulting from the lattice mismatch,on the binding energy of the impurity is included in a variational framework.The binding energy is obtained as a function of the well width,barrier width,and impurity position in the barrier by using a variational method.The result of the present calculation shows that the variational law of the binding energy is similar to that of unstrained materials.
