Abstract

We investigated the stability of Pd/ZnO polar interfaces formed by internal oxidation of Pd-Zn alloys by using high-resolution transmission electron microscopy, electron energy-loss spectroscopy and convergent-beam electron diffraction. At 1273 K, a [Formula: see text] polar interface defaceted and transformed into a curved interface, while another (111)Pd/(0002)ZnO polar interface retained its flatness. The [Formula: see text] polar interface lost some stability over non-polar interfaces at 1273 K, while the (111)Pd/(0002)ZnO polar interface remained stable.

摘要

我们通过使用高分辨率透射电子显微镜、电子能量损失谱和会聚束电子衍射，研究了钯锌合金内氧化形成的钯/氧化锌极性界面的稳定性。在1273 K时，一个[化学式：见原文]极性界面发生解理并转变为弯曲界面，而另一个(111)Pd/(0002)ZnO极性界面保持其平整度。在1273 K时，[化学式：见原文]极性界面相对于非极性界面失去了一些稳定性，而(111)Pd/(0002)ZnO极性界面仍保持稳定。
