TL;DR: 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.

TL;DR: Quantum dots or rings are artificial nanometre-sized clusters that can be fabricated in a semiconductor system by embedding an island of low-bandgap material in a sea of material with a higher bandgap.
Opticalemissionfromsingle,charge-tunablequantumrings
TL;DR: In this article, a single semiconductor quantum ring is loaded with electrons from a reservoir through a tunneling barrier and an additional electron{hole pair is generated by optical excitation, and abrupt shifts in the emission energy as electrons are added one by one.
