项目摘要

9708246 Nielson This research project entitled Dielectric, Calorimetric, and Nonlinear Optical Properties of New Structurally-Predicted Ferroelectrics will continue the search for new ferroelectric materials based on predictions obtained from a structural analysis of current crystal structure data. After identification of potential ferroelectric materials is established, verification involves high temperature synthesis of the materials in polycrystalline form; structural confirmation by x-ray diffraction analysis; material processing, and subsequent measurement of the dielectric and thermodynamic properties of the materials as a function of frequency and temperature. The research topics for undergraduate students involve solid-state synthesis, calorimetry, dielectric measurements, computer programming and interfacing, x-ray diffraction and crystallography, all of which are designed to meet the graduation requirements for students of chemistry and physics. %%% Ferroelectrics are of increasing importance in the fabrication of electrooptic devices, integrated circuits, pyroelectric detectors, piezoelectric transducers and actuators, pyroelectric detectors, piezopositioning devices, and non-volatile memory elements. The technological importance of this area and the considerable industrial need for new ferroelectric materials for an increasing range of applications indicate significant job opportunities for students educated in these areas. ***
9708246 Nielson 这项名为“新结构预测铁电体的介电、量热和非线性光学特性”的研究项目将根据当前晶体结构数据的结构分析所获得的预测,继续寻找新的铁电材料。 确定潜在的铁电材料后,验证涉及多晶形式材料的高温合成; 通过 X 射线衍射分析确认结构; 材料加工,以及随后测量材料的介电和热力学特性作为频率和温度的函数。 本科生的研究课题涉及固态合成、量热学、介电测量、计算机编程和接口、X射线衍射和晶体学,所有这些都是为了满足化学和物理专业学生的毕业要求。 %%% 铁电体在电光器件、集成电路、热释电探测器、压电换能器和致动器、热释电探测器、压电定位器件和非易失性存储元件的制造中变得越来越重要。 该领域的技术重要性以及对新型铁电材料的广泛应用的巨大工业需求表明,在这些领域接受教育的学生有大量的就业机会。 ***
