我们在这里报告的Pt电极的生长同时呈现超平坦的表面(均方根=0.3 nm)和完美的(111)单晶取向。 这些电极通过脉冲激光沉积在钇稳定的氧化锆(111)上生长,使用几纳米厚的钛粘附层。这种高结晶质量的电极允许后续层的生长具有非常减少的变体数量。因此,他们打开前景的各向异性表征的多铁性或磁电材料。作为一个例子,示出了在这样的Pt(111)电极上的磁电GaFeO 3的优化生长。
We report here the growth of Pt electrodes presenting at the same time an ultraflat surface (rms=0.3 nm) and a perfect (111) monocrystalline orientation. These electrodes were grown by pulsed laser deposition on yttrium-stabilized zirconia (111), using a few nanometers thick titanium adhesion layer. Such high crystalline quality electrodes allow the growth of subsequent layers with a very reduced number of variants. They therefore open perspectives for the anisotropic characterization of multiferroic or magnetoelectric materials. The optimized growth of the magnetoelectric GaFeO3 on such a Pt(111) electrode is shown as an example.
