In-gap states and local structures around substitutional defects in La- or Nb-doped n-type SrTiO3

First-principles calculations with DFT+U method were conducted on the local structures and the in-gap electronic states of n-type SrTiO3, whose electron doping was realized by substitution of Sr by La or Ti by Nb. For both La-doped and Nb-doped SrTiO3, cubic structures were proved to be stable e3ven...
