Description

The Periodic Potential Lab solves the time independent Schroedinger Equation in a 1-D spatial potential variation. Rectangular, triangular, parabolic (harmonic), and Coulomb potential confinements can be considered. The user can determine energetic and spatial details of the potential profiles, compute the allowed and forbidden bands, plot the bands in a compact and an expanded zone, and compare the results against a simple effective mass parabolic band. Transmission is also calculated through the well for the given energy range.

Recent Changes:

  • Version 1.0.3: Added predefined material masses, such as GaAs, InAs, InP.
  • Version 1.0.3: Reduced the maximum barrier height to a lower value in square well case.
