The effects of the inverse parablic potential on transition rates in a cylindrical nanowire

Tshipa M., University of Botswana, BW

The effect of the inverse parabolic potential on optical transitions in a cylindrical wire is investigated. The excitation beam is one of circularly polarized light. Evaluation of the matrix elements leads to the selection rule [...]

The effects of confining cup-like and hill-like parabolic electric potentials on the photoionization cross section in a spheroidal quantum dot

Tshipa M., University of Botswana, BW

A theoretical investigation of the effects of the hill-like and the cup-like parabolic electric confining potentials on the photoionization cross section (PCS) in a spheroidal quantum dot are presented. The cup-like parabolic potential intensifies, the [...]
