Abstract

This presentation introduces the “Quantum Dot Lab” on nanoHUB.org to an undergraduate audience. The following items will be covered

  • Analytical solutions to the Schödinger Equations
  • 1D particle in a box solution
  • Analytical integration and normalization
  • Quantum world vs. Macroscopic world
  • 3D particle in a box
  • Optical transition energies
  • Available states
  • Fermi-Dirac Distribution
  • Energy absorption
  • Introduction to a few tool user interface pages in Quantum Dot Lab
  • Exercise 1: Visualization of wavefunctions
  • Exercise 2: Asymmetric quantum dot
  • Exercise 3: Pyramidal quantum dot
  • Polarization dependent absorption
  • Homework assignment

Learning Objectives:

  1. Appreciate that different electron confinement potentials have different analytical solution functions
  2. Step through the simplest particle in a box calculation using sine and cosie functions
  3. Appreciate the meaning of the wavefunction, the square magnitude of the wavefunction and the need for a normalization
  4. Understand that light can couple discrete energy states
  5. Transition can only occur between pairs of available states
  6. Get introduced to some exercises that can be performed with Quantum Dot Lab that cover the above concepts.
