Quantum dots are artificial artificial atoms that confine electrons to a small space. As such, they have atom-like behavior and allow the effects of quantum mechanics to be studied on a length scale approximately 100 times larger than the pure atomic scale. Quantum dots offer application opportunities in optical sensors, lasers, and advanced electronic devices for memory and logic. This seminar begins with an overview of wave and particle properties and motivates the existence of quantum mechanics. He closes the perspective of quantum mechanics with these fascinating new artificial atoms.
