dc.descriptionBased on symmetry constraint that leads to the appearance of nodes in the wave functions of 3-electron systems at regular triangle configurations, it was found that, if the parameters of confinement are skillfully given and if a magnetic field is tuned around the critical point of the singlet-triplet transition, a 2-electron quantum dot can be used as a highly sensitive switch for single-electron transport.
