Abstract

We have theoretically investigated the non-linear I-V characteristics of small quantum dots and rings in a magnetic field where single electron charging and discharging are significant. We find that, for both charging and discharging situations, three types of current steps can occur in the I-V characteristics representing three different types of tunneling events. Physically transparent descriptions are given of the tunneling events that give rise to these steps. Also we present a suggestion to use the magnetic field dependence of the step structures in I-V characteristics to map out directly the energy levels of dots and rings.
