💎 Kronig-Penney Model Simulation: Energy Bands, Band Gaps and Bloch Waves in a Crystal Lattice - 3D Crystal Lattice Bench

An interactive Kronig-Penney crystal: change the barrier height, width and lattice spacing and watch allowed energy bands and band gaps open, see Bloch waves travel through the lattice, and find out whether a material is a metal, semiconductor or insulator.
