Title: Stabilization of orthorhombic phase in single-crystal ZnSnN{sub 2} films

Abstract

We report on the crystal structure of epitaxial ZnSnN{sub 2} films synthesized via plasma-assisted vapor deposition on (111) yttria stabilized zirconia (YSZ) and (001) lithium gallate (LiGaO{sub 2}) substrates. X-ray diffraction measurements performed on ZnSnN{sub 2} films deposited on LiGaO{sub 2} substrates show evidence of single-crystal, phase-pure orthorhombic structure in the Pn2{sub 1}a symmetry [space group (33)], with lattice parameters in good agreement with theoretically predicted values. This Pn2{sub 1}a symmetry is imposed on the ZnSnN{sub 2} films by the LiGaO{sub 2} substrate, which also has orthorhombic symmetry. A structural change from the wurtzite phase to the orthorhombic phase in films grown at high substrate temperatures ∼550°C and low values of nitrogen flux ∼10{sup −5} Torr is observed in ZnSnN{sub 2} films deposited on YSZ characterized by lattice contraction in the basal plane and a 5.7% expansion of the out-of-plane lattice parameter.

  • The 1D-orthorhombic polymer phase of C{sub 60} was originally mentioned in 1995. The present work provides the first direct experimental quantitative evidences of the 1D-polymer chains, clearly seen by single-crystal diffraction. Geometrical details of the [2+2]-cycloaddition rings are compared with those of C{sub 60} dimers and 2D-polymers. Another key structural parameter is the angle of rotation {Psi} of the 1D chains about the polymerization axis. Single-crystal diffraction yields {Psi} {approx} 78{sup o}, whereas accurate synchrotron powder diffraction independently produces a similar {Psi} {approx} 73{sup o}. These values are in qualitative agreement with a former theoretical prediction ({Psi} {approx} 61{sup o}).
  • Isothermal resistance measurements and hot-stage optical microscopy were used to simultaneously follow the loss of oxygen and the disappearance of the twin structure in single-crystal YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} from 590--720{degree}C. Oxygen out-diffusion was found to follow surface-reaction-limited conditions with an activation energy of 1.2{plus minus}0.1 eV. Although the crystal was driven through the orthorhombic-tetragonal phase transformation during the isothermal anneals, no anomalous resistance behavior was observed. This suggests that previous observations of anomalous resistance behavior in bulk ceramics may not be intrinsic to YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}}. The difference between oxygen in-diffusion and out-diffusion kinetics is discussed in relationmore » to the twin structure observed near the orthorhombic-tetragonal phase transformation.« less
