Description:
Article The origin of the two-dimensional electron liquid between LaAlO 3 and SrTiO 3 has been a matter of debate. The authors’ investigation of stoichiometry reveals that only Al-rich LaAlO 3 leads to electron liquid formation, which points to the much discussed polar catastrophe mechanism as its origin.
