Abstract
The transport characteristics of resonant tunneling through self-assembled InAs quantum dots is explored. Changing the tunneling direction of the electrons leads to major differences in their behavior. By analyzing magnetotransport and shot noise measurements, this effect can be ascribed to different dimensionalities in the leads. In particular we are interested in the Fermi-edge singularity, which is studied by its noise and temperature behavior.
