The influence of a laser-field on the exciton binding energy and interband optical transitions in quantum-well wires is calculated by using a variational method and in the effective mass approximation. We conclude that in ...

Using a variational approach, we have investigated mainly, the effect of the hydrostatic pressure, and the wire dimension on the interband optical absorption and the exciton binding energy in a quantum-well wire. We have ...

Using a variational approach, we have calculated the hydrostatic pressure and electric field effects on the donor-impurity related photoionization cross-section and impurity binding energy in GaAs/GaAlAs quantum well-wires. ...

The electric field dependence of polarizability and binding energy of shallow-donor impurities in graded quantum-well wires is calculated by a variational method and in the effective-mass approximation. We have considered ...
