The electron density of states (DOS) of individual nanocrystals as a function of their aspect ratio is studied in the regime of strong quantum confinement by electron tunnelling spectroscopy. We find a broad transition regime, spanning the two- and zero-dimensional geometry, where the DOS function has a rich and variable structure, featuring steps and peaks. The experimental results are supported by electronic-structure calculations.Show less >
