Optical spectroscopy of a two-dimensional electron gas near the metal-insulator transition.
TL;DR: Optical measurements of a two-dimensional electron gas near the metal-insulator transition show that transition is induced by localization of single electrons in the electrostatic potential fluctuations of the remote ionized donors.
