Beschreibungen/Notizen

• The origin of the 2D electron gas (2DEG)stabilized at the bare surface of SrTiO sub(3) (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.
