Abstract
Single electron tunneling via impurity states has been used to probe the local density of states (LDOS) of the emitter of a vertical resonant tunneling device. In this work, we focus on the correlation properties of the LDOS fluctuations. The analysis of the shape of the LDOS-correlation function indicates a reduced effective dimensionality of the electronic correlation in the emitter, which can be explained by the presence of a growth-induced interface in the sample structure.
