In this paper we present a calculation of the binding energy of a donor impurity in a cylindrical GaAs-Ga 0.6Al 0.4As quantum well wire (QWW) as a function of an applied magnetic field for different wire radii and different positions of the donor. The model considers an infinite length QWW with a ca...
