Introduction to Quantum Dots: Theory and Applications

Fri., Dec. 4, 2015 3:00 p.m. - Fri., Dec. 4, 2015 4:00 p.m.

Location: CL 317

Abstract:  Quantum Dots are semiconductor nanocrystals so small that their charge carriers experience quantum confinement. This confinement leads to a discrete set of energy levels analogous to an atom, as opposed to a nearly continuous energy structure as seen in macroscopic matter. Further, the energy structure of a Quantum Dot can be finely tuned during production by controlling its size. For these reasons, Quantum Dots are often referred to as "artificial atoms". The discrete nature of their energy levels give Quantum Dots fascinating optical and electronic properties that lead to a wide range of practical applications. Applications that include fluorescent imaging, light emitting diodes, photovoltaic cells, and quantum computation, among many others. We will investigate the theory behind these fascinating materials, examine how they are produced, and explore some of their applications.
