Semiconductor quantum dots, due to their small size, mark the transition between molecular and solid-state regimes, and are often described as ‘artificial atoms’ (ref 1−3). This analogy originates from the early work on quantum confinement effects in semiconductor nanocrystals, where the electronic wavefunctions are predicted to exhibit atomic-like symmetries, for example ‘s ’ and ‘p ’. Spectroscopic studies of quantum dots have demonstrated discrete energy level structures and narrow… 
Optical emission from a charge-tunable quantum ring
TLDR
It is found that the emission energy changes abruptly whenever an electron is added to the artificial atom, and that the sizes of the jumps reveal a shell structure.

Hidden symmetries in the energy levels of excitonic ‘artificial atoms’
TLDR
Artificial electronic structure is investigated by injecting optically a controlled number of electrons and holes into an isolated single quantum dot, which forms complexes that are artificial analogues of hydrogen, helium, lithium, beryllium, boron and carbon excitonic atoms.

Kondo resonance in a single-molecule transistor
TLDR
The Kondo resonance can be tuned reversibly using the gate voltage to alter the charge and spin state of the molecule and persists at temperatures up to 30 K and when the energy separation between the molecular state and the Fermi level of the metal exceeds 100 meV.

Spatially Resolved Visible Luminescence of Self-Assembled Semiconductor Quantum Dots
TLDR
Cathodoluminescence was used to directly image the spatial distribution of the quantum dots by mapping their luminescence and to spectrally resolve very sharp peaks from small groups of dots, thus providing experimental verification for the discrete density of states in a zero-dimensional quantum structure.
