Abstract
We present an experimental study of the electron wave function in InAs/GaAs self-assembled quantum dots. Magneto-tunneling spectroscopy is employed as a non-invasive probe to produce two-dimension al images of the probability density of an electron confined in a quantum dot. The images reveal the el liptical symmetry of the ground state and the characteristic lobes of the h igher energy states of the dots.
