Abstract

Nonequilibrium transport in a few-electron quantum dot artificial atom in the absence of spin-flip energy relaxation was investigated. The double electron tunneling (DET) and excited state(ES)-ES tunneling resulting in fluctuation in the total spin were discussed. Results showed that these transport processes could not be explained by Coulomb blockade theory and are due to the absence of effective spin relaxation in a quantum dot.
