Electron microscope images showing two of the ordered structures formed in the experiments (IMAGE)
Caption
The electron microscope images show two of the ordered structures formed in the experiments. Atoms inside the quantum dots are resolved by the microscope and it can be seen that they are aligned throughout adjacent dots. A model of the device used for the measurement of the electronic properties is shown at the bottom right. The superlattice lies between two electrodes while an ionic gel on top (gate electrode) is used to accumulate carriers in the active material.
