Electronic reconstruction and transport properties in SrTiO3/Sr1−xLaxTiO3 superlattice

First-principles calculation was used to study the electronic structure and transport properties of SrTiO

/Sr

superlattice. We found that in comparison with bulk Sr

TiO

electronic structure of the superlattice is dramatically changed and strongly depends on the SrTiO

thickness. This electronic reconstruction induces multi-type carriers which exhibit different transport characteristics. The possible functional enhancement is demonstrated.
