POWRE: Fabrication of (Ba,Sr)TiO3 and Related Materials by a Reactive Process

妇女在研究和教育中的职业机会(POWRE)项目致力于利用反应过程制造和表征作为溅射靶材的超细颗粒(Ba，Sr)TiO_3(BST)和相关材料，如BaTiO_3(BT)和SrTiO_3(ST)。这些薄膜材料是下一代计算机芯片非常重要的介电元件。这些溅射靶材用于生产薄膜。有人建议使用热线在压制的粉末压坯中触发这些反应过程。将进行热力学、动力学研究以及反应机理研究。将对显微组织进行表征，并将其与工艺参数关联。该反应过程经济，使用廉价的原材料，能耗低。该反应过程也有工业放大的可能性。这对这位新的原则调查员在开始她的职业生涯时的职业发展潜力很重要。这项工作的教育部分将主要侧重于两项活动：为高年级/研究生修改一门现有的材料加工课程，并让本科生参与高级加工研究领域。预计POWRE项目将为未来具有重大工业兴趣的研究提供机会，使这位新教师能够专注于一套新材料，同时提高她在薄膜沉积领域的专业知识。

This Professional Opportunities for Women in Research and Education (POWRE) project addresses fabrication and characterization of ultrafine grained (Ba,Sr)TiO3 (BST) and related materials, such as BaTiO3 (BT) and SrTiO3 (ST) as sputtering targets using a reactive process. These materials in thin film condition are very important dielectric constituents for the next generation computer chips. These sputtering targets are used in producing thin films. It is proposed to trigger these reactive processes in pressed powder compacts using a hot wire. The thermodynamics, kinetic studies as well as reaction mechanism studies will be performed. The microstructure will be characterized and correlated to the processing parameters. The reactive process is economical, uses inexpensive raw materials, and has low energy requirement. The reactive process also has possibilities of industrial scaling up. This is important to the career development potential for this new Principle Investigator in starting up her career. The education component of the work will focus mainly on two activities: modification of an existing material processing course for the senior/graduate students and involvement of undergraduates to the advanced processing research area. It is expected that this POWRE project will provide opportunities for future research with significant industrial interest, allowing this new faculty member to focus on a new set of materials while advancing her expertise in the thin film deposition area.
