Quantum Dots are manmade artificial atoms that confine electrons to a small space. As such they have atomiclike behavior and enable the study of quantum mechanical effects on a length scale that is around 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 starts with an overview of wavelike and particle like properties and motivates the existence of quantum mechanics. It closes the quantum mechanics point of view with these new fascinating artificial atoms.
