چکیده

We demonstrate the heteroepitaxial growth of phase-pure bronze-phase TiO2 films using pulsed laser deposition on MgAl2O4 single-crystal substrates. While cubic substrates with smaller lattice parameters favors stabilization an out-of-plane-oriented anatase phase, and use larger leads to formation rutile lies in a narrow intermediate range where bronze phase is stabilized. X-ray diffraction shows that b-axis oriented out-of-plane, while a–c plane within film plane. The show twinned domains due their monoclinic structure are aligned along all four in-plane directions lattice. In subsequent step, grown top MgAl2O4-buffered MgO single crystals order route stabilize variety bronze-type unique, open, one-dimensional framework normally may allow for investigation its basic functional properties related ion diffusion cannot otherwise be studied easily other crystal forms.

Synthesis and properties of a-axis and b-axis oriented GdBa2Cu307-s high 7’, thin films

We report the growth and properties of a-axis oriented GdBa,CusO,-a high T, thin films on (100) SrTi03 substrates by dc magnetron sputtering. It is found that GdBa,Cu,O,-s films on (100) SrTiO, exhibit a-oriented growth at higher substrate temperatures compared with YBaQtsO,-& films. By utilizing low-temperature-grown u-axis GdBazCu,O,_.s films (200 A in thickness) as a self-template, pure a-ax...

Structural phase transition in epitaxial perovskite films

Three different film systems have been systematically investigated to understand the effects of strain and substrate constraint on the phase transitions of perovskite films. In SrTiO3 films, the phase transition temperature Tc was determined by monitoring the superlattice peaks associated with rotations of TiO6 octahedra. It is found that Tc depends on both SrTiO3 film thickness and SrRuO3 buff...
