Abstract: In this work we have systematically investigated the evolution of structure and stoichiometry in SrCuO 2 films grown on TiO 2 -terminated SrTiO 3 substrates as a function of the substrate temperature. Depending on the growth temperature SrCuO 2 /SrTiO 3 films can exhibit either a pure tetragonal high-pressure phase, or a pure orthorhombic low-pressure phase, or a mixed phase. Our results indicate that at low substrate temperatures the non-equilibrium state of the growth process is responsible for the stabilization of the metastable tetragonal high-pressure structure in SrCuO 2 thin films grown on ( 0 0 1) SrTiO 3 substrates, whose lattice matches the metastable structure. In addition, at higher substrate temperatures thermodynamics become dominant over other factors and the SrCuO 2 thin films are stabilized in the thermodynamically stable orthorhombic phase.
