3 By completing the Periodic Potential Lab in [[Resource(5065)]], you will be able to:
4
5 a) understand the Kronig-Penney model and the formation of energy bands and energy gaps due to the underlying periodic interaction potential
6
7 b) understand the concept of the effective mass
8
9 c) create your own Kronig-Penney solver.
