ABSTRACT

The present work investigates the effect of topological defects in quantum dots on the effective g*- factor. Using the energy spectrum, we derived the exact analytic expression for the effective g*-factor and studied the variation of the effective g*-factor with the disclination parameter. It was shown that, in the case of n=0,l=-1, as the magnetic field increases, the effective g*-factor changes sign and increases, approaching the value n=0,l=0. In the case of n=0,l=1, it decreases and approaches n=0,l=0. In the case of n=0,l=0, the effective g factor remains constant as the magnetic field changes.

Keywords: effective g*-factor, quantum dot,disclination.
