Spatial Mapping of the Electron Eigenfunctions in InAs Self-Assembled Quantum Dots by Magnetotunneling

Abstract

We use magnetotunnelling spectroscopy as a non-invasive probe to produce two-dimensional spatial images of the probability density of an electron confined in a self-assembled semiconductor quantum dot. The images reveal clearly the elliptical symmetry of the ground state and the characteristic lobes of the higher energy states.
