    Resistivity measurements show that SrTiO3 / LaTiO3 / SrTiO3 heterostructures remain metallic even for single unit cell LaTiO3 layers. Hall resistances of all heterostructures are nonlinear functions of the applied field. The Hall data is analyzed in terms of a two-layer model, indicating that a low-mobility layer exists at the LaTiO 3 / SrTi3 interface, while carriers with mobilities approaching 10 000 cm2 /V s are present deep in the SrTiO3 substrate.
