RUI: Systematic Prediction and Characterization of New Ferroelectric Materials

小行星9310461 本计画系关于建立一个跨学科的大学生研究实验室，以系统地预测和表征新的无机铁电材料。 这个为期三年的项目预计将大大增加已知铁电材料的数量，目前已知铁电材料的数量约为200种。 铁电体在电光器件、集成电路、热释电探测器和压电换能器的制造中越来越重要。 该项目包括根据对以前发表的晶体学数据的分析预测新材料的铁电行为;这些材料在高温下形成多晶形式;通过X射线分析验证材料具有预期的结构;样品处理;随后测量这些材料的介电和热力学性质作为温度的函数，以确认预测的铁电性质。 该项目旨在提供一系列有吸引力的本科研究课题，并鼓励参与者从事物理和化学职业。 ***

9310461 Nielson This project is concerned with the establishment of an interdisciplinary undergraduate research laboratory for the systematic prediction and characterization of new inorganic ferroelectric materials. The three-year project is expected to increase significantly the number of known ferroelectric materials which now stands at about 200. Ferroelectrics are of increasing importance in the fabrication of electrooptic devices, integrated circuits, pyroelectric detectors, and piezoelectric transducers. The project involves the prediction of ferroelectric behavior in new materials based on analysis of previously published crystallographic data; the high temperature formation of these materials in poly crystalline form; verification by X-ray analysis that the materials have the expected structure; specimen processing; and subsequent measurement of the dielectric and thermodynamic properties of these materials as a function of temperature to confirm the predicted ferroelectric property. The project is designed to offer a series of attractive undergraduate research topics and will in addition encourage the participants to follow careers in physics and chemistry. ***
