| dc.description | Results for the binding and infrared transition energies associated with the ground and first few excited states of a hydrogenic-donor impurity in a cylindrical GaAs-Ga1-xAlxAs quantum-well wire are presented. A variational approach for the trial envelope wave functions corresponding to each donor state is used within the effective-mass approximation. Results are obtained for several wire radii in the case of donors located at the axis of the quantum-well wire. We find that the impurity states 2p(x) (2p(y)) and 3p(x) (3p(y)) are not bounded when the wire radius is sufficiently small, a behavior similar to the one found for impurities in quantum-well heterostructures. | |
