✦ Synopsis

The effective electron Lande ´factor in GaAs2Ga 1Àx Al x As rectangular quantum well wires, under magnetic fields applied along the wire axis, is studied by taking into account the non-parabolicity and anisotropy of the conduction band within the Ogg-McCombe effective Hamiltonian. Confinement effects on the electron wavefunctions are explored in order to evaluate its influence on the behavior of the effective Lande ´factor. Calculations for the electron g k factor in GaAs2Ga 1Àx Al x As rectangular quantum well wires are compared with the previous theoretical results obtained for GaAs2Ga 1Àx Al x As cylindrical quantum well wires. Such comparison clearly indicates the influence of the wire shape on the electron Lande ´factor in GaAs2Ga 1Àx Al x As quantum well wires.

The binding energy of a shallow hydrogenic impurity in a spherical quantum dot under hydrostatic pressure with square well potential is calculated using a variational approach within the effective mass approximation. The effect of conduction band non-parabolicity on these energies is also estimated.
