Abstract

We have studied the single-electron transport spectrum of a localized level embedded into a double-barrier resonant tunneling structure. The experimental spectrum shows clear deviations from the Fock-Darwin model indicating a broken circular symmetry. We interprete our observations in terms of the existence of an additional multiple-charged impurity in the vicinity of the quantum dot.
