We analyzed the electronic structure of perfect and defective strontium titanate for the SrO-termination surface. Figure 9(a) displays the total density of states (TDOS) for the perfect surface STO(001) with SrO-termination. The deep valence states are due to Sr 4 p and O 2 s orbitals and undoped STO with SrO-termination is an insulator. …Web
