      abstract     = {The interfaces between two condensed phases often exhibit
                      emergent physical properties that can lead to new physics
                      and novel device applications and are the subject of intense
                      study in many disciplines. We here apply experimental and
                      theoretical techniques to the characterization of one such
                      interesting interface system: the two-dimensional electron
                      gas (2DEG) formed in multilayers consisting of SrTiO3 (STO)
                      and GdTiO3 (GTO). This system has been the subject of
                      multiple studies recently and shown to exhibit very high
                      carrier charge densities and ferromagnetic effects, among
                      other intriguing properties. We have studied a 2DEG-forming
                      multilayer of the form [6unitcells(u.c.)STO/3u.c.ofGTO]20
                      using a unique array of photoemission techniques including
                      soft and hard x-ray excitation, soft x-ray angle-resolved
                      photoemission, core-level spectroscopy, resonant excitation,
                      and standing-wave effects, as well as theoretical
                      calculations of the electronic structure at several levels
                      and of the actual photoemission process. Standing-wave
                      measurements below and above a strong resonance have been
                      exploited as a powerful method for studying the 2DEG depth
                      distribution. We have thus characterized the spatial and
                      momentum properties of this 2DEG in detail, determining via
                      depth-distribution measurements that it is spread throughout
                      the 6 u.c. layer of STO and measuring the momentum
                      dispersion of its states. The experimental results are
                      supported in several ways by theory, leading to a much more
                      complete picture of the nature of this 2DEG and suggesting
                      that oxygen vacancies are not the origin of it. Similar
                      multitechnique photoemission studies of such states at
                      buried interfaces, combined with comparable theory, will be
                      a very fruitful future approach for exploring and modifying
                      the fascinating world of buried-interface physics and
                      chemistry.},
