Investigation of magnetic field effects on binding energies in spherical quantum dot with finite confinement potential

The magnetic effects on the energy states and binding energies of the ground and higher excited states of the spherical quantum dot are studied theoretically for various potential depths. Also, Zeeman transition energies in the case of Delta M = 0, +/- 1 are carried out. The results show that the energy states and binding energies in small dot radii are insensitive to the increase of magnetic field. In the case of negative m, in the strong confinement region, the binding energy increases as the confinement potential decreases. In the case of positive m, the binding energy decreases with the decrease of the confinement potential. (C) 2017 Elsevier B.V. All rights reserved.
