CAREER: Soft and Hard Chemical Routes to Nanoscale Metal Chalcogenide Materials

化学系的分析和表面化学项目将这个职业奖授予西北大学，以研究纳米过渡金属二硫属化物材料的合成和性质。 凭借该奖项，Teri Odom教授将探索无机类富勒烯MX2（M = Nb，Ta; X = S，Se）材料的路线，以及通过控制尺寸，结构和嵌入化学来改变电子特性的策略。 主要的兴趣是如何表面和体结构和系统的有限尺寸可以影响集体现象的性质，如电荷密度波和超导性。 变温扫描隧道显微镜（STM）和导电原子力显微镜（AFM）将用于电子表征。 奥多姆教授还将纳米技术融入课堂活动，使高中科学教师参与研究项目。 她正在开发纳米科学课程，包括获得尖端仪器和本科生早期接触研究。 Teri Odom教授将开发基于过渡金属二硫属化合物的富勒烯样纳米材料的制备方法，并通过使用原子和高光谱分辨率技术研究电子特性。 这些研究的结果提供了有关材料性质的基本信息，这些材料性质控制着超导性和表面态的电子电荷捕获。 教育部分将扩大对研究和纳米科学的认识，并为高中科学教师提供新的学习机会。

The Analytical and Surface Chemistry Program in the Division of Chemistry makes this Career award to Northwestern University to investigate the synthesis and properties of nanoscale transition metal dichalcogenide materials. With this award, Professor Teri Odom will explore routes to inorganic, fullerene-like MX2 (M = Nb, Ta; X = S, Se) materials and strategies for varying the electronic properties through control of size, structure and intercalation chemistry. Of primary interest is how the surface and bulk structure and finite size of a system can influence the properties of collective phenomena, such as charge density waves and superconductivity. Variable temperature scanning tunneling microscopy (STM) and conducting atomic force microscopy (AFM) will be used for electronic characterization. Professor Odom will also integrate nanoscale technology into classroom activities and enable participation of high school science teachers in research projects. She is developing curriculum in nanoscience that includes access to cutting-edge instrumentation and early exposure of undergraduate students to research. Professor Teri Odom will develop methods for the preparation of fullerene-like, nanoscale materials based on transition metal dichalcogenide compounds and investigate the electronic properties through the use of atomic and high spectroscopic resolution techniques. The results of these studies provide fundamental information about materials properties that control superconductivity and electronic charge trapping by surface states. The education component will broaden awareness of research and nanoscale science and open new learning opportunities for high school science teachers.
