Abstract

Various spin sequences occuring during the charging of realistic vertical quantum dots were discussed using three-dimensional (3D) density functional model. It was found that maximal spin alignment was not any guarantee for a peak, at half-shell filling. The analysis showed that in the third shell, a clear dip at N = 7 electrons followed by a peak at N = 8 or 9, was the signature of maximum spin alignement at half-shell filling.
