Illustration of a synchrotron‐radiation X‐ray experiment on a LaAlO 3 /SrTiO 3 heterostructure: Absorption of linear polarized photons is used to determine the orbital splitting of 3d orbitals (upper‐right) of titanium ions (red spheres); surface X‐ray‐diffraction allows a structural refinement of the systems. M. Salluzzo and co‐workers combine these two techniques on page 2333 to reveal a structural and electronic reconstruction of the interface, correlated to the formation of a two‐dimensional electron gas.
