⚡ Band Structure — Kronig-Penney E-k Diagram (2D)

2D Canvas electronic band structure simulator: a real Kronig-Penney (delta-comb) nearly-free-electron plane-wave model computes E(k) bands, bandgap and Fermi level, classifying materials as conductor, semiconductor, or insulator.

A 2D Canvas companion to the 3D band-structure simulator: diagonalizes a real Kronig-Penney (delta-comb) nearly-free-electron Hamiltonian at each wavevector to plot the E(k) band diagram. Adjust the potential strength and Fermi level to watch the bandgap open and the material reclassify between conductor, semiconductor, and insulator.
