Lateral super‐lattices along the surface of a semiconductor can generate mini‐band structure for distances of the order of 1000 Å or less. The detailed gap structure depends noticeably on the charge in the structure. Under conditions of strong population inversion, synergetic switching behavior and space‐charge waves can be expected to occur.
