Two-dimensional electron gas generated by La-doping at SrTiO3(001) surface: A first-principles study
We carried out first-principles calculations to study the electronic properties of SrO-terminated and TiO2-terminated SrTiO3(001) surfaces with La-doping at the surface. We find that an intrinsic lower-lying state at the SrO-terminated surface can accommodate a two-dimensional electron gas (2DEG). B...
