Comparing grain growth experiments and simulations in 3D Open
Experimental investigations in STO ceramics revealed a grain growth anomaly, that presumably originates in the interface anisotropy of these materials. However, the influence of anisotropic grain boundary (GB) properties on grain growth be…
Orientation‐dependent surface composition of <i>i</i> n situ annealed strontium titanate Open
The surface composition of polycrystalline niobium‐doped strontium titanate (SrTiO 3 : Nb) is studied using X‐ray photoelectron emission microscopy (XPEEM) for many grain orientations in order to characterise the surface chemistry with hig…
Changes in macroscopic behaviour through segregation in niobium doped strontium titanate Open
The electrical properties of electroceramics are largely governed by their complex microstructure which must be precisely controlled for applications (as, for example, sensors, actuators and capacitors). In this study, the dependence of ni…
