      abstract     = {One of the observed and reported phenomena in heterogeneous
                      interfaces of perovskite oxides isthe presence of a two
                      dimensional electron gas (2DEG). In this study, the
                      imperfect interface that isformed between LaLuO3 and SrTiO3
                      was studied. It was found using x ray diffraction pole
                      figurethat LaLuO3 is deposited on SrTiO3 in a two-domain
                      structure with alternately charged layers parallelto the
                      surface. First-principles calculations reveal that even
                      though the lattices of the two materialsdo not match, an
                      increase of the total potential is found at the interface
                      between the twolattices. Due to this increased potential,
                      electrons are drawn to the interface; since the interface
                      isnot perfectly epitaxial, 2DEG is not formed and instead
