title = "Optical evidence for the impurity band nature of the metal-insulator transition in GaAs",
abstract = "Far infrared magneto transmission measurements on n-type GaAs doped near the metal-insulator transition show evidence for the impurity ls-2p± optical transition in both the insulating and the metallic states and no cyclotron resonance at low temperatures. The ls-2p± absorption line-shape varies smoothly through the magnetic field induced metal-insulator transition.",
