Spatial mapping of the electron eigenfunctions in InAs self-assembled quantum dots by magnetotunnelling

We use magnetotunneling spectroscopy as a non-invasive probe to produce 2D 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...

Description
Summary:We use magnetotunneling spectroscopy as a non-invasive probe to produce 2D 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.
