We focus our attention on the non-linear transport regime. We demonstrate that the peak amplitudes in the I-V characteristics show a dramatically different behaviour as a function of the magnetic field, depending on the value of the angular momemtum of the dot state through which tunnelling occurs. The investigation allows us to probe details of the quantum dot wavefunctions and to distinguish tunnelling through localised states related to impurities or to quantum dots. |
