Abstract

First-principles calculation was used to study the electronic structure and transport properties of SrTiO₃/Sr_1-xLa _xTiO₃ superlattice. We found that in comparison with bulk Sr_1-xLa_xTiO₃ electronic structure of the superlattice is dramatically changed and strongly depends on the SrTiO ₃ thickness. This electronic reconstruction induces multi-type carriers which exhibit different transport characteristics. The possible functional enhancement is demonstrated.
