We show that confinement together with intrinsic polarization induce hole doping of the CuO2 plane in the proposed SrTiO3/[SrO-La2CuO4-SrO]/LaAlO3 heterostructure without resorting to chemical substitution, using the generalized gradient approximation and its combination with Coulomb correlation U....
