Description

Background
Quantum dots (dots) are semiconductor nanostructures that tie excitons up in three spatial directions. Sometimes referred to as "artificial atoms," or "quantum dot atoms," is a new concept proposed in the 90 s of the 20 th century. This confinement can be due to electrostatic potential (generated by external electrodes, doping, strain, impurities), the interface of two different semiconductor materials (e.g., in self-assembled quantum dots), the surface of the semiconductor (e.g., semiconductor nanocrystals), or a combination of the three.
