“…Different studies, both theoretical and experimental [16][17][18][19][20][21][22][23], reveal the important influence of electric and magnetic fields on the properties of nanostructured systems, which allows for the discovery of new properties and the development of new applications. On the other hand, Stepanyan and his collaborators [20] obtained, using the variational method, the electron states in a nanowire of cylindrical symmetry in the presence external electric field, homogenous and perpendicular to the axis of the system. In this work, the authors were able to demonstrate that there is a dependence of energy with the electric field and the radius of the system.…”

In this work, the electron states corresponding to a semiconductor quantum well wire grown on a GaAs/AlGaAs matrix with a cylindrical symmetry, in the presence of an external electric field which is homogenous and perpendicular to the axis of the system, is obtained. This study takes into consideration the partial and total confinement of the charge carriers, and assumes T=0 K. The model on which this is based considers a system of parabolic bands, which unfolds in a system of sub-bands due to confinement. In addition, the selection rules for intraband and interband optic transitions are studied.
