1-D Quantum Crystal Applet Description

1-D Quantum Crystal Applet is a quantum mechanics simulation that shows the behavior of a particle in a one-dimensional crystal (or lattice, or periodic potential). Periodic potentials are used to model electron behavior in a crystal. At the top of the applet you will see a graph of the potential, along with horizontal bands showing the energy levels. By default, the potential is an array of square wells (the Kronig-Penney model). Below that you will see the probability distribution of the particle's position. Below the particle's position you will see its band structure, displayed as a dispersion curve; this is a graph of energy versus the crystal momentum k, with the energy bands shown as gray in the background. The particle's energy is shown as a red horizontal line. Give 1-D Quantum Crystal Applet a try to see what it can actually do for you!
