Abstract

Closed and open quantum dots are low-dimensional electron systems with different strength of coupling to the two-dimensional environment. In the case of a the closed dot, only transport by tunneling is possible. Our work, on the the other hand, investigates the transport of open quantum dots strongly coupled to the surrounding two-dimensional electron system. The open dot show peculiar peaks in their magnetoresistance. We compare experimental results with those of a semi-classical model using trajectories in a parabolic potential. Using a velocity distribution of the incoming electrons based on Fermi-Dirac statistics we can explain the temperature dependence of the peak heights.
