Abstract

The origin of the 2D electron gas (2DEG)stabilized at the bare surface of SrTiO3 (001) is investigated. Using high‐resolution angle‐resolved photoemission and core‐level spectroscopy, it is shown conclusively that this 2DEG arises from light‐induced oxygen vacancies. The dominant mechanism driving vacancy formation is identified, allowing unprecedented control over the 2DEG carrier density.
