Imaging Electrons in a Single-Electron Quantum Dot

A scanning probe microscope (SPM) can be used to image a single-electron quantum dot at liquid-He temperatures by recording the Coulomb blockade conductance as a charged SPM tip is scanned above. The Coulomb blockade produces a ring in the image as the first electron is added to the dot. If the tip is sufficiently close to the surface, simulations show one may be able to extract the shape of the electron wave function inside the dot from Coulomb blockade conductance images with a resolution exceeding the size of the tip perturbation.
