      abstract     = {For certain conditions of layer thickness, the interface
                      between GdTiO3 (GTO) and SrTiO3 (STO) in multilayer samples
                      has been found to form a two-dimensional electron gas(2DEG)
                      with very interesting properties including high mobilities
                      and ferromagnetism. We have here studied two trilayer
                      samples of the form [2 nm GTO/1.0 or 1.5 unit cells
                      STO/10 nm GTO] as grown on (001)
                      (LaAlO3)0.3(Sr2AlTaO6)0.7, with the STO layer thicknesses
                      being at what has been suggested is the critical thickness
                      for 2DEG formation. We have studied these with Ti-resonant
                      angle-resolved and angle-integrated photoemission and find
                      that the spectral feature in the spectra associated with the
                      2DEG is present in the 1.5 unit cell sample, but not in the
                      1.0 unit cell sample. We also observe through core-level
                      spectra additional states in Ti and Sr, with the strength of
                      a low-binding-energy state for Sr being associated with the
                      appearance of the 2DEG, and we suggest it to have an origin
                      in final-state core-hole screening.},
