Mapping of few-electron wave-functions in semiconductor nanocrystals - evidence of exchange interaction


The influence of the tip-substrate bias induced electric field in a scanningtunneling-spectroscopy experiment on charged InAs nanocrystals is studied. Calculating the ground and first excited many-particle state for five electrons occupying the quantum dot reveals a Stark-induced reordering of states by increasing the electric field strength. It is shown… (More)
