Abstract Equilibrated interfaces between Ni and yttrium stabilized zirconia (YSZ) were formed by solid-state dewetting of thin Ni films on the (111) surface of YSZ single crystals at 1350 °C and an oxygen partial pressure of P(O2) = 10−20 atm. The atomistic structure of the equilibrated solid-solid Ni [ 1 ¯ 10 ] 111 ∥ YSZ [ 1 1 ¯ 0 ] 111 interface was determined by monochromated and aberration-corrected scanning transmission electron microscopy, using different techniques. It was found that due to the large lattice mismatch between Ni and YSZ the interface reconstructs, and adopts a unique structure which consists of a high density of misfit dislocations. However, despite the large lattice mismatch, this interface is not incoherent. The interface was confirmed to be cation terminated, which is probably due to the low oxygen partial pressure used to reach equilibrium.

摘要 Ni 和钇稳定氧化锆 (YSZ) 之间的平衡界面是通过在 1350 °C 和氧分压 P(O2) = 10− 下对 YSZ 单晶 (111) 表面上的薄 Ni 膜进行固态去湿而形成的。 20 大气压。平衡的固固Ni [ 1 ¯ 10 ] 111 ∥ YSZ [ 1 1 ¯ 0 ] 111 界面的原子结构是通过单色和像差校正的扫描透射电子显微镜，使用不同的技术确定的。发现由于 Ni 和 YSZ 之间的大晶格失配，界面重建，并采用由高密度错配位错组成的独特结构。然而，尽管晶格失配很大，但该界面并非不连贯。接口被确认为阳离子终止，
