Introduction to Quantum Dot Lab
31 Mar 2008 | Online Presentations | Contributor(s): Sunhee Lee, Hoon Ryu, Gerhard Klimeck
The nanoHUB tool "Quantum Dot Lab" allows users to compute the quantum mechanical "particle in a box" problem for a variety of different
confinement shapes, such as boxes, ellipsoids, disks, and pyramids. Users can explore, interactively, the energy spectrum and orbital shapes of new quantized states, as well as quickly view these artificial atoms have their own particular optical absorption properties. This presentation introduces the particle in the box problem in 1D and 3D, and explores the concept of occupied and empty states, allowed transitions, and optical absorption. Students are encouraged to duplicate all the simulation results shown in the presentation. Exercises and a project or homework assignment are given at the end of the presentation.
