9909963StemmerThis award supports Susanne Stemmer from Rice University in a collaboration with Christian Ruessel of the Department of Glass Chemistry at the University of Jena, Germany. The collaboration studies the titanate family of molecules, such as barium titanate, which have attracted attention recently for many important applications such as information storage devices or tunable microwave devices. Techniques that provide information about the distribution of defects within these microstructures are currently lacking. The cooperative work funded here will develop a method to quantify the point defect chemistry and dielectric properties of titanates almost down to the atomic level by means of electron energy-loss spectroscopy. The project benefits from synergy of expertise in defect-property relationships of multicomponent oxides and expertise in the synthesis of oxides from highly reduced melts. The research will also benefit from sharing characterization facilities and materials-synthesis facilities.

9909963Stemmer 该奖项支持莱斯大学的 Susanne Stemmer 与德国耶拿大学玻璃化学系的 Christian Ruessel 合作。 该合作研究了钛酸盐分子家族，例如钛酸钡，该分子最近在信息存储设备或可调谐微波设备等许多重要应用中引起了人们的关注。 目前缺乏提供有关这些微结构内缺陷分布信息的技术。 这里资助的合作工作将开发一种方法，通过电子能量损失光谱来量化钛酸盐的点缺陷化学和介电性能，几乎达到原子水平。 该项目得益于多组分氧化物缺陷-性能关系方面的专业知识和从高度还原熔体合成氧化物方面的专业知识的协同作用。 该研究还将受益于共享表征设施和材料合成设施。
